Back analysis assisted by a genetic algorithm

The following paper presents an idea and the results of trial computations regarding the problem of back analysis technique applied to parameter investigation based on triaxial test results. The management of the searching process was entrusted to a simple genetic algorithm. Inversion of a standard interpretation procedure was based on error minimization between computed and experimental stress-strain relations. In the paper, a case application of the proposed procedure to parameter calibration for elasto-plastic constitutive model is presented.
