Abstract

The main goal of this work is to investigate whether material properties can be obtained using an inverse problem technique. The inverse problem technique used in this paper consists of three main parts: First, a set of input data (time series and parameters) and the objective data (time series) to be reproduced. Second, a model capable of simulating the requested data. Third, optimisation of the modeling parameters by filling simulated data with the objective data. The suggested methodology of the inverse problem tcchnique seems promising for estimating material properties but requires that: (I) All measurements errors must be known; (2) The (measured) signals itself should deliver enough input power into the system; (3) The simulated objeeti\'e data should be sensitive enough for changes in material properties.
