Lecture 18: Modeling of Elasto-Plastic and Creep Response II

Om kurset

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 Instructor: Klaus-Jürgen Bathe
