The stacking sequence connects local material behaviour with structural response. Enter the correct property source, angle and thickness for each layer, then check the resulting stiffness and any intended symmetry. For sandwich constructions, the core has a distinct physical role; its thickness and shear properties should not be treated as an incidental extension of a face ply.
4.1 Turn ply definitions into laminate decisions.

Shared laminate stiffness drives this membrane/CLT path. Failure criteria are independent comparisons, not blended models. Fatigue is a separate assessment.

SIMULATION selects this case and its analysis model; the case owns its applicable cycle and input references.

Ply angles and thicknesses, stiffness, mass and ply properties.
Geometry → Mechanical
Part shape and dimensions, thickness or section definition, and model-specific geometric inputs. Each selected case consumes only the dimensions its model supports.

ASTM-based teaching geometry, not certification. Grips, tabs, alignment and physical test validity are not simulated.
03.3 / Workflow focus
Connected engineering recordPly stack
Set material references, angles and thicknesses. The stack defines laminate stiffness, mass and reference properties.
CLT and FSDT
ABD properties support laminate response. Finite-plate studies select CLT or FSDT within their supported boundary and study limits; static plate bending requires FSDT.
Failure and interfaces
Eligible CLT cases use the released failure criteria. Coupled delamination belongs to the supported layerwise section path with calibrated interfaces, not every plate solver.
Separate analytical studies
Open-hole strength, linear-shear LaRC04 initiation, axial creep and uncertainty use the linked laminate reference state. They do not automatically inherit process or progressive-damage histories.
Design exploration
Carpet maps and bounded optimization compare candidates. Apply a candidate and rerun the appropriate analysis; a saved result does not update itself.

Chapter review
A checked laminate has traceable layer definitions and a total thickness consistent with the intended structure.
