Micromechanics for Materials Science
Lecture & Exercises

Materials show a multitude of heterogeneities due to their microstructure, defects, or grain boundaries in a generalized sense. In micromechanics, one investigates the impact of these microscale heterogeneities or defects on a material's overall mechanical properties and performance at the macroscale. This micro-to-macro transition formally proceeds by appropriate averaging processes and is called homogenization. Starting with a brief introduction to continuum mechanics, this lecture focuses on fundamental analytical and computational homogenization techniques.

Overview

This lecture deals with fundamentals of micromechanics in the framework of elasticity and plasticity theory. Important topics include

  • Basics of elasticity, plasticity, viscoplasticity and crystal plasticity,
  • Theory of configurational force (including J-Integral),
  • Micro-macro transition and homogenization, and
  • damage mechanics.
