Creep
Time-dependent deformation under sustained load
code_aster
In development.
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.

What comes out
- Creep strain accumulation
- Time to allowable deformation
- Stress relaxation history
- Remnant life indication

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.
