Laminated airframes need ply-aware criteria — not metal von Mises alone. HENSTRUCT includes CLT ABD stacks plus Tsai–Hill/Wu, Hashin, and Max Stress/Strain failure checks.
Define the stack honestly
Record ply thicknesses, orientations, and material cards. Wrong ABD input produces confident but wrong MoS.
Pick criteria to the failure mode
Fibre vs matrix dominated failures need different criteria. Hashin and Tsai–Wu are common review languages for aerospace buyers.
Handoff from CAD/mesh
Freeze outer mould line in HFOIL, prepare structural mesh in HENMESH, then solve ply stresses in HENSTRUCT.
