Abstract

This paper presents a method to determine parameters in constitutive equations, used for the description of the mechanical behaviour of composites. The method is based on: numerical analysis, strain distribution measurements and systems identification techniques. The method is especially suitable to study the behaviour of inhomogeneous materials. By means of a simulation it will be shown that for a solid with a varying fibre direction it is possible to estimate the stiffness parameters as well as the local fibre directions from one single test.
