Capabilities / 02.3

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.

Actual short-fiber GUI with orientation inputs and a spatially distributed fiber preview

Cox shear-lag teaching setup with Fa = 0.15 and Fp = 0.35. The 3D illustration uses normalized fiber lengths; it is not a resolved RVE or a physical-scale micrograph.

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.

02.3 / How to use it

What to set, compare and check
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.

What to check and where it applies

  • One compatible model is selected per Micro recipe; models are not blended.
  • 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.
