From experiments to predicting the component behavior in solid mechanics

Hartmann, Stefan GND

Modern computer programs for the calculation of the deformation behavior of components under external loads require physical models. These so-called material models are either available for specific materials, or they have to be developed for this purpose. The parameters occurring in the mathematical equations must then be adapted to special measurements. Then, it is possible to implement these material models in computer programs in order to predict complex structures or components. This overall process requires knowledge of executing experiments, of concept formation for developing models, of the numerical implementation of mostly coupled partial differential equations, as well as of identifying the material parameters occurring in the models. In addition, concepts for verification and validation of the calculations must be taken into account and further developed. The entire procedure is relevant in many other scientific fields. Here, we concentrate on problems of the mechanics of solid bodies.
