3 unit(s)

S. Pietruszczak

Basic concepts of plasticity: yield criteria; isotropic and kinematic hardening; flow and deformation theories; fundamental postulates of plasticity; uniqueness of the solution. Elasticperfectly plastic formulations: failure criteria (metals/ frictional materials); derivation of constitutive matrix. Isotropic strain- hardening models for cohesive-frictional materials: concepts of volumetric and deviatoric hardening. Modeling of the behaviour of brittle-plastic materials (concrete). Limit analysis: lower/upper bound theorems.
