Damage

Progressive material degradation

code_aster

In development.

This module is phase 2 — the next module after cfd. The solver behind it is chosen and its capability is known. SHD Sim is available today.

What it is

Materials degrade before they separate: microcracks accumulate and stiffness falls. Continuum damage models carry a damage variable that softens the material as it grows, which captures the run-up to failure rather than only the moment of it — and brings mesh sensitivity that has to be managed.

What this analysis needs from you

  • A damage model with calibrated parameters, usually from test data
  • Careful meshing — softening localises into whichever elements are smallest
  • code_aster

Typical uses

  • Ductile failure prediction in forming and crash
  • Concrete cracking in civil structures
  • Composite progressive failure
  • Predicting where failure initiates, not just where stress is highest

Industries

Sectors where this analysis is routinely asked for.

  • Composites manufacturing
  • Automotive crash
  • Defence
  • Research & academia

What comes out

  • Damage initiation sites
  • Stiffness degradation history
  • Failure progression sequence
  • Energy absorbed

Backend

code_aster

Chosen for this analysis type, with its capability verified against the module plan — not decided later.

Status

Phase 2 — the next module after CFD. Telling us you need this analysis moves it up the order — modules are sequenced by who is waiting for them.
