Abstract

The analysis of any engineering structure is based on three steps - the choice of a material model, of a structural model and of an analytical or numerical method. All three items are interlinked, and the improvement, for example, of the structural model demands the improvement of the material behavior model and vice versa. In this contribution is reported on the engineering approaches to the material modelling. The models are mostly phenomenologically that means the real structure of the material is ignored. On the other hand, they are much simpler in comparison with micro-mechanically or physically based equations.

In the first part some general remarks on the principles of material modelling will be given. Three approaches to formulate material equations are presented. The main attention is paid to the inductive approach. In the final part some examples showing the application of the engineering models of material behavior to the analysis of thin-walled structures (beams, plates, shells) are given.
