Abstract:
Constitutive model calibration and uncertainty quantification are essential tasks to ensure reliable simulation results in computational solid mechanics. The field of constitutive model calibration has re-emerged as a focus of current research activities due to the ongoing development of full-field measurement methods. Furthermore, model discovery has gained popularity, allowing researchers not only to calibrate the material parameters of a constitutive model, but to simultaneously determine the appropriate constitutive model from experimental data. In this context, data-driven approaches have become promising alternatives to traditional constitutive modeling techniques. Similarly, the quantification of uncertainties has significantly risen in research interest in recent years. This includes not only determining the uncertainties associated with material parameters, but also efficiently predicting uncertainties in the mechanical response of components in engineering simulations.
Contributing to these developments, this minisymposium aims to bring together researchers who are actively working in the broad field of computational solid mechanics, focusing on constitutive model calibration or discovery, as well as uncertainty quantification. Particularly, we welcome contributions dealing with multi-physical background.
