The response calculation adds geometry, supports and loading to the material description. Check compatibility before interpreting an output and keep the baseline unchanged during comparison. CREATE and DISCOVER can organize candidate designs, but the final interpretation depends on the equations and constraints evaluated for those candidates.

Euler–Bernoulli beam · Linear static · ASTM D7264 · Three-point flexure · Procedure A load
Beam bending uses effective laminate axial stiffness, the linked section geometry, support span and applied loading. Euler–Bernoulli deflection excludes transverse shear deformation, roller contact and indentation. Ply stress recovery for rectangular laminate coupons is separate from section-level beam stress recovery.

03.5 / Workflow focus
Connected engineering recordPlate and beam response
Use the released CLT/FSDT finite-plate or membrane/beam path with compatible dimensions, loads and supports. Buckling, modal and static bending are distinct study choices.
Cylinder formulations
Thin-wall membrane and layerwise thick-wall elasticity have different load and process limits. Donnell axial buckling is a separate thin-shell study with an explicit knockdown factor.
Sections and joints
Layerwise sections, lap joints and sandwich bending have their own geometry and interfaces. The analytical Volkersen / Goland–Reissner study is a separate identical-adherend elastic approximation.
Failure and notches
The five existing criteria support eligible CLT first-ply / progressive calculations. LaRC04 linear-shear initiation and calibrated open-hole strength are separate studies, not additional progressive choices.
Fatigue
S–N models predict life from calibrated data. Residual stiffness / strength requires independently fitted retention laws in its separate study; neither automatically changes optimization properties.
Creep, shape and uncertainty
Reference-state studies explore time response, prescribed-eigenstrain free release and bounded ABD sampling. Their scope, inputs and output handoffs are listed below.
Keep validation data connected
Run the selected Simulation after relevant edits. Review model assumptions, stale-result warnings, convergence and calibration before interpreting the result.
