Current Workbench models and compatibility

This theory library includes wider research formulations. Check the released model directory for selectable models, required inputs, limits and exercises. The event-driven RVE branch is not enabled in hosted Workbench.

Models, equations, figures, and cross-references
01 / Elastic foundation

Constituent to effective stiffness

Continuous and discontinuous fibers; rule of mixtures, Halpin–Tsai, Mori–Tanaka, self-consistent formulations; aspect ratio; global orientation; Chou Fa/Fp; constituent-limit recovery; compliance and stiffness matrices.

Open elastic theory →
02 / Discontinuous fibers

Random ends, Weibull strengths, and critical clusters

This reference describes the Henry–Pimenta event-driven RVE formulation. It is not enabled in hosted Workbench; the released Cox elastic short-fiber model has a narrower supported scope.

Open discontinuous-fiber theory →
03 / Textile architectures

Tows, fabrics, and architecture corrections

Plain weave, 2×2 twill, 4/5/8-harness satin, basket, leno, biaxial NCF, and triaxial braid with warp–weft averaging, crimp, interlacing, stitch, binder, and bias-angle effects.

Open fabric theory →
04 / Multiphysics and defects

Fillers, voids, and thermophysical response

Filled-resin and hybrid homogenization, explicit and dilute directional void treatment, density, specific heat, orthotropic conductivity, directional CTE, validation checks, and linked references.

Open filler and void theory →
05 / Damage and failure

CDM and composite failure

Continuum damage mechanics, Tsai–Wu and Hashin criteria, recovered endpoint properties, degradation, and failure progression.

Open failure theory →
06 / Unified r15 handoff

Generated properties enter progressive laminates

Each physical ply independently selects automatic property resolution, embedded constituent micromechanics, or direct measured data. The generated pristine 3D property set then enters the common damaged-ABD and failure-redistribution solver.
