Identification Aspects of Inhomogeneous Materials
This paper presents an inverse method to determine parameters in constitutive equations. The method is especially suitable to study the mechanical behavior of inhomogeneous materials. The method is based on: numerical analysis, strain distribution measurement and system identification. By means of simulations it will be shown that for a solid with a varying fiber direction it is possible to estimate stiffness parameters a well as the local fiber directions from one single test.
