Compatible formulations
The Models browser lists rule-of-mixtures variants, Halpin–Tsai, Chamis, Mori–Tanaka, Hashin–Rosen, self-consistent, woven bridging and Cox elastic short-fiber choices. Architecture determines which choices are available.

Predict effective behavior from
constituents and architecture.
Choose a released architecture-compatible homogenization model, inspect its reference ply properties, and carry those properties into the laminate.
Architecture and micromechanics model selections sit beside the live microstructure preview.

02.3 / How CDS solves it
From engineering question to evidenceShort-fiber scope
Cox shear-lag elastic studies use prescribed geometry and orientation. The event-driven Henry–Pimenta RVE and its stochastic discontinuous-fiber failure route are not enabled in the hosted release.
Ply-property handoff
The selected Micro recipe supplies reference properties to its linked plies. Shared material or Micro edits can change multiple laminate calculations.
Explore and compare
Use an exercise or supported property sweep to compare model assumptions, constituent limits and sensitivity. Predicted strengths and teaching defaults are not qualified allowables.
Workbench availability: released models, inputs and compatible study paths. The wider theory library includes reference formulations not available in every Workbench solve.

- Cox short-fiber predictions are elastic. Event-driven RVE and stochastic discontinuous-fiber failure remain disabled.
- Calibration and constituent-limit checks are required before engineering use.
