Numerical Scheme for Solving Elasto plastic Identification Problens of Material Properties in Geotechnical Engineering

The regularized least square iterative algorithm has been presented for the estimation of material parame-ters of complicated structures. The scheme for calculation of sensitivity coefficients has been given The algorithmhas overcome the difficulties caused by the ill posedness of inverse problems SeveraI techniques have been used toensure rationality of the solution and the stability of the convergence. The numerical examples show that the algo-rithm presented here is practical and efficient.
