The field of experimental mechanics has been reduced at German universities over several decades. This trend has been reinforced by the field of computational mechanics. However, if we look at the last few years, a number of institutes have set up small laboratories dedicated to experiments on solid materials. There are several reasons for this. Firstly, experts have developed a number of mathematical models (constitutive calculation models) that describe material behaviour and need to be validated by experimental observations. Secondly, the field of material parameter identification has evolved significantly, especially considering inhomogeneous deformations using finite elements. Therefore, the parameters of the model need to be calibrated against the experimental data. Thirdly, the experimental techniques and measurement technology have been significantly improved to enable microscopic and macroscopic in-situ observations.

The challenges to be overcome are the development, exploration and dissemination of new experimental techniques in multiscale and multiphysics applications (chemical, mechanical, thermal, magnetic and electrical). In this respect, robust optical measurement systems have been improved, for example to determine thermal and mechanical fields on the surface, but also in the interior.

The objectives of the expert committee are:

Develop a platform for the joint exchange of knowledge in the field of solid mechanics. The particular focus is on experiments that are carried out for model calibration or model validation. The discussion deals with the questions: Who carries out which experiments? Where are the test facilities located? What testing options are available? and Who can provide which resources and knowledge (experience)? Further objectives are the compilation of publications, the provision of own publications and the provision of selected experimental data.
