Material behavior - Plasticity

Continuum mechanics, algebra and tensor analysis (1^st year Mechanics course)

Going beyond the framework of linear elasticity under the assumption of small perturbations:
•  Discover the main types of nonlinear behavior of materials
•  Know the thermodynamic framework in which the general models must fit
•  Master several behavior models

•  Demonstration on simple tensile tests
•  Thermodynamics of irreversible processes as a framework for writing behavior models
•  Three examples of elasto-(visco)-plasticity models
•  An example of an elasticity-damage model

•  Know how to identify the appropriate behavioral model for the problem at hand
•  Model complex problems with advanced behavioral models
•  Propose behavior models adapted to new materials
