Choose the structure
| Geometry ID | Idealization | Primary results |
|---|---|---|
| 1 | Rectangular laminate plate | Deflection, moments, buckling factor, natural frequency |
| 2 | Circular laminate cylinder | Radial/hoop/axial response using shell or Hyer formulation |
| 3 | Composite beam section | Centroid, I2/I3, EI, strain energy, deflection, buckling, frequency |
Plate boundaries
For the current Workbench plate module, choose Plate theory = CLT or FSDT in CASES. FSDT adds transverse shear and rotary inertia using shared laminate properties. Read the FSDT formulation, current scope and dedicated examples →
Geometry entries 8–11 assign the x0, x1, y0, and y1 edges independently: 1 simply supported, 2 fixed, or 3 free. Plate stiffness comes from the active laminate D matrix; mass and frequency use the calculated effective laminate density.
Cylinder formulations
Cylinder coordinates are axial x, hoop arc-length y, and radial z. Geometry entry 4 selects 1 for the engineering shell solution or 2 for the Hyer formulation. Pressure, axial force, and torque remain in the load-scaler group.
Beam sections
Geometry entry 12 selects rectangle, I section, circular tube, rectangular tube, or solid circle. The section dimensions occupy entries 14–21; end conditions occupy 22–23. The solver reports both geometric moments of inertia and laminate-effective EI.
Output interface
- The structural summary contains cylinder, plate, and beam section, response, energy, buckling, and frequency results.
- The cylinder load history contains pressure, force, torque, resultants, and radial traction.
- The cylinder stress-recovery table contains final radial coordinates and recovered stresses.
Engineering scope. These are reduced-order plate, cylinder, and beam calculations for sizing, comparison, and workflow integration. Validate boundary assumptions and model fidelity before certification or safety-critical use.
