The majority of the characteristics and parameter values of constitutive
laws for the continuum mechanical description of solids are governed by
It is a common but usually cumbersome practice to obtain information on a
material law and its parameters by performing series of experiments.
In addition to cost and time consuming manipulations such experimental
methods often do not yield a fundamental insight into the micromechanical
mechanisms responsible for the material behavior.
An alternative approach is presented which uses the finite element method for investigating the micro-structure of certain materials and for developing models for a computational derivation of the macroscopic (continuum mechanical) description. The present contribution shows the application of such methods to metal matrix composites (MMCs) and phase transforming metals.
