Workflow / 03.1 Materials

Build a trusted
materials foundation.

Organize source-aware constituents, vendor records, prepregs, adhesives, cores, sandwich systems, diffusion data, cure kinetics, crystallization kinetics, reaction heat, and process shrinkage into reusable engineering records.

Trace the selected input path

Stored ply properties bypass Micro. Mixed stacks keep both paths. Gray blocks are not selected. Geometry, process schedules and other model records are omitted here for clarity; a real run must include all required references.

Fatigue uses intact CLT endpoint stresses and measured S–N calibration. It is evaluated separately from Run and progressive failure. The dashed handoff is not active: optimization still uses current properties until a degradation law is supplied.

Teaching illustration only. Controls change this diagram, not your database or Workbench simulation. Use the Workbench solver for stresses, failure and qualified comparisons.

03.1 / Workflow focus

Connected engineering record
01

Source-aware constituents

Keep elastic, strength, density and transport data with their units, sources and calibration basis.

02

Material models

Assign calibrated cure, crystallization, modulus or transport models through the material record. A model sitting in the tree does not contribute until it is linked.

03

Measured or predicted plies

A laminate ply can use a stored material or linked Micro recipe. Check the resolved properties before selecting the structural study.

04

Data handoff

Materials feed Micro and the linked laminate. Compatible transport studies evaluate the selected material laws; not every structural study includes processing.

Independent model records can be linked together through material inputs. A saved model must be assigned to a material before it contributes to a simulation.
