Continuum Mechanics : large deformations formalism
Master Physique appliquée et ingénierie physiqueParcours Modélisation mécanique pour l'énergie et l'environnement
Description
Motion of continuum body in lagrangian description and in eulerian description. Properties of the mapping function F of the initial configuration onto the current configuration. Construction of the strain tensors in finite strain theory (Green, Almansi, Hencky, etc.) and the associated stress tensors (Cauchy, Kirschhoff, PKII).
Introduction of materials derivative of a tensor field. Local and global conservation of mass, momentum and energy, applied in solids and fluid statics and dynamics. Variational formulations and principle of virtual power.
Applications in elasticity, newtonian fluids, Navier-Stockes equation, local state thermodynamics, inequality of Clausius-Duhem.
Energy theorems and introduction to finite element method.
