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.

Translate constituents into
effective material behavior.
Choose a released architecture-compatible homogenization model, inspect its reference ply properties, and carry those properties into the laminate.
One cell. A whole fabric.
Explore plain, twill and satin yarn surfaces in Micro, Live Stack, CREATE and DISCOVER. Switch between one repeat and 2 × 2 or 3 × 3 cells, then rotate and zoom. CREATE carries the selected weave and woven bridging model into SIMULATE, subject to your license.
Captured from the Workbench components in a local preview, September 17, 2026. Missing yarn dimensions are inferred and listed under Geometry inputs & assumptions. These are periodic surface illustrations—not measured textile CAD, solid exports or a mesh-based solver. Effective properties are calculated separately by the selected micromechanics model.

03.2 / Workflow focus
Connected engineering recordShort-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.
