Panels and Beams

Unstiffened Panels

The most basic panels are sheet metal and laminates. These concepts do not have stiffeners or cores to provide buckling stability.

Sandwich Panels

Useful for structures that have biaxial compression and/or shear loading causing buckling. A commonly used aerospace composite panel concept, but not for primary loaded commercial airframes.

Stiffened Panels

Useful for structures that are mostly under uniaxial loading. Open sections such as ‘I” are often used for airframe wing skin and closed sections such as ‘Hat’ for fuselage skin.

Grid Stiffened Panels

Used for metal biaxial and shear loaded structure such as an aircraft rib. These concepts have many dimensions to optimize.


Beams can be analyzed and sized. Specific beam stiffness formulation and failure analyses are performed. Modeled with 1D elements.

Fastened and Bonded Joints

FEM Joint

A FEM joint is a HyperX derived entity. They are generated automatically from the intersection of structural zones.  One- and two-member line joints are used for load processing.

Edge Allowable Joint

Design of a joint begins with edge allowable joints. FEA loads are extracted in the joint coordinate system and compared to pull off and shear allowables.

fastened joint

Fastener types, diameters, spacing, and number of rows are sized. Analysis include fastener bearing and bearing-by-pass on the laminate.  NASA 5020 analyses include pull off and torque.

rivet joint

Rivet types, diameters, spacing, and number of rows are sized. Analysis is based on allowables from testing rivet and sheet metal combinations. 

Bonded joint

Adhesive material, thickness, overlap length, and taper angle are sized. Analyses include linear/nonlinear peel and interlaminar shear stresses; and VCCT energy solution for disbonds.

Composite Laminates

Effective Laminates

A smeared representation of a laminate. Three variables: ply material, laminate thickness, and laminate angle % in the 0/45/90 directions.

Discrete Laminates

Layup stacking. Four variables: ply material, thickness, angle, and stacking order. Primarily used to represent imported laminates from the FEM defined with data such as Nastran PCOMP.

Laminate Families

Layup stackings defined as columns in a spreadsheet or table with shared plies. Sizing produces manufacturable laminates that have continuous sequence of layers laid up over a part. 

Sizing Optimization

Rapid Sizing

In a few seconds size many FEM zones to all load cases with different materials and panel concepts. Variable bounds automatically set.

Detail Sizing Panels

In a few minutes rigorously size many structural zones to all load cases with different materials for a given panel or beam concept. User controls variable bounds.

Detail Sizing Joints

In a few minutes rigorously size many structural joints to all load cases. Evaluate different joint concepts. User controls variable bounds.

Interactive Optimization

HyperX’s interactive optimization approach facilitates the user to start with an open design space with millions of candidates and funnel down to a preferred design.

Trade Studies

Conceptual Design

During conceptual phase of design explore alternative configurations and architectural layouts.

Preliminary Design

During preliminary phase of design evaluate the performance of different materials and panel & joint concepts.

Detailed Design

During detailed design phase establish the optimum dimensions, thicknesses, and laminates of each part of your structure. 


Upload HyperX results to a database hosted in either the cloud or on company servers. Users and project managers can view the results using typical web browsers from a laptop or smart phone.


Streamline Workflows

Model Centric User Interface

Interact directly with the model and HyperX entities at all times. The user has multiple ways to manage visibility, selection, organization, and assignment.

Process Monitor

As an analysis or sizing run is executing, the process monitor displays a summary progress of completed results, as well as logs, warnings, and errors with suggested corrections.

Scripting API

Automate repetitive process tasks through code or seamlessly incorporate HyperX into larger software environments.

FEM WorkFlow

FEM Import

Import your FEM to analyze and size each FEM property zone. Leverage preprocessor specific data to set up structure entities.

FEA Loads Import

Extract FEA computed element forces per load case. Process large solution output data sets very efficiently to define factored design-to loads for analysis and sizing.

FEA Design Loads

FEA unfactored load cases are multiplied by factors to establish design-to loads for analysis and sizing.

FEM Update

After optimizing the model zones, HyperX automatically updates FEM properties with new shell thicknesses, laminates, and beam properties.

FEA Loads Cycling

HyperFEA™ automatically iterates FEA solutions and HyperX sizing. Converge load paths and enforce global deflection, buckling, or frequency requirements.

FEM Reimport

As the design matures, the initial FEM geometry, architectural layout, and/or mesh will be redefined. The new model can be reimported into the HyperX project keeping its previous setup data intact.

FEM Panel Modeling Techniques

Flexible modeling approaches are supported. Smeared models do not require stiffeners to be modeled, while discrete modeling techniques include stiffeners explicitly defined with beams and shells.

Analysis Workflow

Analysis Property

Set the types of analyses to execute. Analysis criteria can be individually toggled on/off, providing flexibility and visibility of their assignment on the FEM.

Load Property

Process thousands of element forces into zone design-to loads to analyze and size. Envelope load cases and tailor the level of conservatism.

Panel Segments

Stiffened panel segments are defined from attaching skins and stiffeners. Failure analyses such as cross section crippling require that the skin and stiffener are treated as a system.


Automatically generate a detailed local FEM from the global FEM for verification. HyperFEMgen™ will make the mesh, apply boundary conditions, and apply the global loads to the local FEM.

Design Workflow

Design Property

Use Design Properties to select between rapid sizing, detail sizing, or analysis only. Identify material, laminate and optimization bounds per variable.

Material Database

Store material data in HyperX to use in analysis and sizing. Establish sophisticated laminate allowables, bearing-bypass envelopes, and correction factors in a shared database to deploy to team members.

Fastener and Rivet Database

Store fastener and rivet data in HyperX for joint analysis and sizing. Define this data in one place and efficiently share among a team of collaborating engineers.

Zone Generation

Split large FEM property areas into many analysis/sizing zones at geometric boundaries such as intersecting structure. Optimize zone shapes and sizes to load gradients.

Section Cut

Calculate cross-section stiffnesses, center of gravity, and shear center. Apply minimum values that are enforced when sizing. Report summation of “built up” section cut loads, per loadcase.



Generate Laminate Families

Generated families have stacking sequences and ply counts that are tuned to provide low weight and manufacturable solutions for specific zones or structures.

Import Laminate Families

Existing families can be imported to HyperX and used for composite optimization.

Study Angle Percentage

Ply angle (0⁰,45⁰,90⁰) percentage limits in laminate optimization influence both weight and producibility. HyperX’s design study tool is used to examine the trends.

Study Laminate Families

HyperX’s laminate family design study tool is used to analyze weight and manufacturability trends resulting from different drop patterns, ply shapes and Main Stacking Sequences (MSS).


Ply Sequencing

The minimum-weight laminate for a zone is not always the most producible. Ply sequencing assembles zone laminates into producible plies on a structure.

Ply Scoring

Producibility of plies is assessed by considering two primary features: ratio of perimeter length to ply area, and orientation of fibers relative to ply boundaries.

Ply Visualization

Review ply shapes, drops, and stacking sequence as well as cores and core taper in HyperX before exporting for manufacturing.

Ply Modification

Users can manually modify plies after generation. HyperX provides several tools for easy editing. Updated margins can be generated after ply modification.

Composite Stiffened Panels

Stiffened Panel Ratios

Cross section ratio bounds can be used to ensure that the optimized geometry is producible. Designs with short, squat or tall, slender geometry can be filtered out.

Composite Panel Section View

HyperX goes beyond finding an optimum layup for each stiffened panel object (web, cap, etc) and determines ply connectivity between objects.

Stiffened Panel Dimension Studies

Height and stiffener spacing can be constrained by producibility as well as subsystem requirements. HyperX can study weight impact due to these constraints.

CAD/CAM Interface

AFP Data Import

As-manufactured fiber directions and thickness for AFP structures on double curvature can vary from the original design. HyperX can import this data for re-analysis.

CAD Boundary Export

HyperX can optimize “organic” boundaries of plies and zones to suit structural loads. The boundaries of these zones or plies can be exported in a CAD format.

CAD Ply Export

Plies optimized on the FEM in HyperX must be mapped to CAD software to be finalized for manufacturing.

Metal Structures


HyperX generates producible designs for machined grid stiffened panels (such as orthogrid) by considering factors such as machining tolerance and geometry rules.

Dimension Overrides

Although machined structures can support variable thicknesses, considerations such as fastener grip length require specific dimensions to be specified in HyperX

Stock Sizes

Non-machined metal parts must respect available material stock sizes to be producible. HyperX can enforce that stock sizes are used when performing optimization.


Analysis Consistency

Consistency from PDR to Part Release

Use HyperX in all phases of vehicle design to maintain consistency in workflow and implemented analysis.

FEM Modeling Progression of Stiffened-Panels

Design cycle consistency is provided by HyperX’s thermoelastic formulation of stiffened panels that works with many different FEM modeling techniques.

Material and Fastener Database

Maintain and deploy verified and test validated material and fastener properties required for certification.

Database Templates

Save all project level data and method preferences in a HyperX Database Template. Use these templates as a starting place for all team members to ensure one source of truth for analysis and sizing.

Enterprise Deployment
