Workflow / 03.2 Micromechanics

See how the constituents
change the ply response.

Start with the constituents and reinforcement architecture. Choose a compatible homogenization model from the released choices, inspect the predicted reference ply properties, then use them in the laminate.

See how a unit cell repeats.

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.

DISCOVER: repeat a twill unit cell into a fabric patch.
DISCOVER: repeat a twill unit cell into a fabric patch.
CREATE: carry the weave into a connected laminate recipe.
CREATE: carry the weave into a connected laminate recipe.

Captured from the Workbench components in a local preview, September 17, 2026. Missing yarn dimensions are inferred and listed under Geometry inputs & assumptions. These views illustrate periodic surfaces; they are not measured textile CAD, solid exports or a mesh-based solver. Use the selected micromechanics model for the separate effective-property calculation.

About this workflow view

All blocks keep the CREATE / DISCOVER / SIMULATE positions, with Equipment below Geometry; unused records remain disconnected. This changes the view only, not the exercise records. The diagram shows the setup, not solved results.

∑ Used models & submodels

Only models assigned to records used by this exercise are listed here. The full-layout option preserves the supplied starter records; no Workbench records are changed.

Rule of mixtures · T700 / EP180 UD · Unidirectional lamina

One compatible homogenization model per Micro recipe. Separate recipes compare models; their predictions are not blended.

Study scope and limitations

Ideal continuous, aligned reinforcement with zero voids. This is a teaching comparison, not a measured material allowable.

Model availability depends on your license. The preview does not run or save a calculation.

What connects to the next step
01

Choose a model for the architecture

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.

02

Short-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.

03

Carry the properties into the ply

Link the Micro recipe to a ply to use its reference properties. Before changing a shared material or Micro record, check which laminates use it; the edit can affect several calculations.

04

Explore and compare

Work through an exercise or a supported property sweep to see how the assumptions and constituents change the result. Check constituent limits and sensitivity. Predicted strengths and teaching defaults are not qualified allowables.
