Optimization as a Tool for the Inverse Identification of Parameters of Nonlinear Material Models

Popis výsledku v původním jazyce

At present, optimization methods are finding application in many technical as well as nontechnical fields. One of the possible applications of optimization procedures is in the identification of formerly unknown parameters of nonlinear constitutive relationships of construction materials which are used in numerical simulations of the behaviour of built structures. In this respect, optimization constitutes a certain counterweight to other soft-computing methods which also include methods of identification based on the exercise of artificial neural networks. The topic of the following contribution is the description of the possible connection of a computational system based on the finite element method with an optimization tool, and an analysis of the identification of the mechanico-physical and fracture mechanical parameters of a material model for concrete based on the Willam-Warnke yield surface from an experimentally-measured loading curve. The individual steps of this inverse identi
