 MINI-CURSO METODOS MATEMATICOS DA MECANICA 

Sanda Tigoiu

(Faculty of Mathematics and Informatics, University of Bucharest)

 

Title:

"Finite elasto-plasticity with structural inhomogeneities.

Theory and applications"

 

Contents:

-1. Fundamental concepts in Continuum Mechanics, related to finite elasto-plasticity.

-2. Constitutive assumptions in multiplicative finite elasto-plasticity, based on the current relaxed configurations: elastic type constitutive relation and evolution equations for plastic deformation and internal variables

 -3. Material symmetry in finite elasticity and in finite elasto-plasticity.

Application to orthotropic and tranversely isotropic materials.

-4. Rate type boundary value problems. Applications to bifurcations of homogeneous deformations in crystal plasticity.

-5. Second order type finite-plasticity: elastic and plastic distortion and connection. Theorem for the representation of connections.

-6. Mathematical models for defects existing at the micro-structural level, geometric description and balance equation for associated micro-forces.

-7. Non-local models for elasto-plastic materials with dislocations.

Applications.

 

The lectures include proposed exercises and problems, and detailed notes are annexed to give certain detailed explanations which are necessary for a better understanding of the exposures.

Wednesday 18 May from 14:30 to 16:00

Thursday 19 May from 14:30 to 16:00
