SHD Sim FEA

Creep

Time-dependent deformation under sustained load

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

Metal held under load at high temperature keeps deforming with time, even below yield. The rate depends strongly on both temperature and stress, so an assessment is really about the hours at condition rather than the peak load, and design life is measured in tens of thousands of hours.

What this analysis needs from you

  • A creep law with fitted constants for the specific material
  • A temperature field and a duty history in real time
  • code_aster

Typical uses

  • Boiler and steam pipework life assessment
  • Gas turbine hot section components
  • Bolted joints that relax at temperature
  • Remaining-life estimates for plant past its design life

Industries

Sectors where this analysis is routinely asked for.

  • Power generation
  • Petrochemical
  • Gas turbines
  • Glass & ceramics processing

What comes out

  • Creep strain accumulation
  • Time to allowable deformation
  • Stress relaxation history
  • Remnant life indication

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.
