Administered by:

Introduction to computational plasticity: historical perspective, physical motivation, rate independent plasticity, rate dependence, creep, rheological methods. 1D mathematical model: yield criterion, flow rule, loading/unloading conditions, isotropic and kinematic hardening models, 1D elasto-plastic boundary value problem. Computational aspects of 1D elasto-plasticity: integration algorithms, operator split, return mapping, incremental elasto-plastic BVP, consistent tangent modulus. Classical model of elasto-plasticity: physical motivation, classical mathematical model of rate-independent, elasto-plasticity yield criterion, flow rule, loading and unloading conditions. Computational aspects of elasto-plasticity: integration algorithms, operator split, the trial elastic state, return mapping, incremental elasto-plastic BVP, consistent tangent modulus. Plane strain Von Mises elasto-plastic model: continuum, integration algorithm, operator split, the trial elastic state, return mapping, incremental elasto-plastic BVP, consistent tangent modulus. Generalisations and applications of plasticity.
