From Raw Properties to Full Analysis in Four Steps
Each step feeds the next. The materials you define become lamina, the lamina become the plies you stack, and the stack becomes an ABD matrix.
Start building for free1. Define Materials
Enter fiber and matrix properties, or copy standard materials like T300 carbon and epoxy from the library.
2. Build Lamina
Combine a fiber and matrix to predict unidirectional ply properties using micromechanics.
3. Construct Laminate
Stack plies at different angles to define your laminate stacking sequence.
4. Analyze
Get ABD stiffness matrices, engineering constants, and failure predictions from Classical Lamination Theory.
See It in Action
A complete composite analysis workflow, from material properties to structural results.
Standard Material Library
Browse a library of fibers, matrices, and lamina with textbook-grade properties. Copy standard materials like T300, E-glass, AS4, and S2-glass to your workspace, or add your own test data.

UD Lamina from Fiber + Matrix
Select a fiber and matrix, set fiber volume fraction, and instantly calculate unidirectional ply properties. Choose from Chamis, Hopkins-Chamis, Halpin-Tsai, CCA, Puck, and Rule of Mixtures.
Fabric Lamina from Weave Geometry
Build woven fabric ply properties from fiber, matrix, and weave pattern. Choose plain, twill, or satin weaves and get equivalent lamina stiffness from RVE-based homogenization.
Laminate Stacking & CLT Output
Define your stacking sequence with drag-and-drop layers. Toggle symmetry, set ply angles and thicknesses, and see the full ABD stiffness matrix and engineering constants update in real-time. No waiting, no recalculate button.
Progressive Failure
Push a laminate past first ply failure. Each failed ply is degraded ply-by-ply, the ABD matrix rebuilt, and the laminate re-solved until it reaches ultimate failure. Choose from Max Stress, Max Strain, Tsai-Hill, Tsai-Wu, Hashin, Puck, Cuntze, Sun, and Edge criteria.
Structural Analysis
Take a finished laminate into a part. Analyze composite beams, sandwich panels, plates, and cylindrical shells for bending, buckling, and failure margins.
All Dashboard Features
Every tool in the dashboard, free. No credit card, no trial, no limits.
UD Lamina Builder
Combine fiber and matrix with six micromechanics models (Chamis, Hopkins-Chamis, Halpin-Tsai, CCA, Puck, Rule of Mixtures) to calculate ply properties.
Fabric Lamina Builder
Build woven fabric laminas with unit cell geometry. Calculate effective stiffness by homogenizing the warp and weft yarns over the unit cell.
Laminate Builder
Build your stacking sequence with symmetry toggle, multi-lamina support, and real-time ABD matrix calculation.
Laminate Load
Apply mechanical, thermal, and moisture loads to predict laminate response under combined loading.
Drag & Drop Layup
Reorder plies by dragging them into place. Add, remove, or rearrange layers and watch the laminate properties update live.
First Ply Failure
Predict failure with nine criteria: Max Stress, Max Strain, Tsai-Wu, Tsai-Hill, Hashin, Puck, Cuntze, Sun and Edge. Identify the critical ply and mode.
Ply Stresses & Strains
View ply-by-ply stresses and strains in both global and material axes under applied laminate loads.
Progressive Failure
Load laminates beyond first ply failure with ply discounting to trace damage progression up to ultimate failure.
Ply Calculator
Calculate fiber areal weight, cured ply thickness, void content, and laminate weight from constituent properties.
Beam / Column
Bending stiffness and Euler buckling loads for composite beams and columns.
Engineering Constants
Membrane and flexural engineering constants derived from ABD stiffness matrices, plus thermal and moisture expansion coefficients.
Core Materials
Build a library of core materials (foam, honeycomb, balsa) with the properties needed for sandwich panel analysis.
Sandwich Panel
Analyze sandwich panels with composite facesheets and a core material for stiffness and strength.
Plate
Deflection under pressure and buckling under compression for rectangular composite plates, simply supported or clamped.
ABD Matrix
Full extensional, coupling, and bending stiffness matrices computed from Classical Lamination Theory.
Tube / Cylinder
Structural analysis of composite cylindrical shells including buckling under axial compression and external pressure.
