Inspect four separated plies, consolidate them into a symmetric balanced laminate, then apply in-plane tension. Fiber orientation changes laminate extensional stiffness and the transverse strain response.
• 3D scene parts: four resin-bound plies; oriented fiber bundles; in-plane tensile grips; material and loading directions; extensional stiffness readout. • Controls: four-ply sequence ([0 / 0 / 0 / 0], [0 / 90 / 90 / 0], [θ / −θ / −θ / θ]), angle-ply θ (0–90 °), fiber volume fraction (0.2–0.7), applied axial strain (0.001–0.005), separate plies for inspection. • Live readouts: lamina longitudinal modulus; lamina transverse estimate; laminate axial modulus; axial laminate stress; transverse strain; load · 20 mm wide × 1 mm thick. • Guided experiments: Unidirectional axial layup; Cross-ply balance; Angle-ply shear compliance. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.

Linear elastic classical extensional lamination calculation for the listed symmetric balanced sequences, with approximate constituent mixing rules. No strength, damage, delamination, curing, thermal stress or buckling prediction. The 3D strain is magnified; separated plies are an inspection view. Try the preset experiments, then compare the live readouts with the equations.
No. Off-axis response requires transformed stiffness or compliance.
No. Failure and damage are not calculated by this elastic model.
