Lecture 18: Modeling of Elasto-Plastic and Creep Response II
Topics: Modeling of elasto-plastic and creep response II
- Strain formulas to model creep strains
- Assumption of creep strain hardening for varying stress situations
- Creep in multiaxial stress conditions, use of effective stress and effective creep strain
- Explicit and implicit integrations of stresses
- Selection of size of time step in stress integration
- Thermo-plasticity and creep, temperature-dependency of material constants
- Example analysis: Numerical uniaxial creep results
- Example analysis: Collapse analysis of a column with offset load
- Example analysis: Analysis of cylinder subjected to heat treatment
