In particular, a thermomechanical as well as a fracture mechanical system is considered, where novel formulations are introduced for both. The corresponding discrete contact formulations are based on a variationally consistent mortar approach adapted for NURBS discretized and hierarchical refined surfaces. Finally, the capabilities of the proposed framework are demonstrated within numerous numerical examples UR - https://www.ksp.kit.edu/9783731506164 UR - https://directory.doabooks.org/handle/20.500.12854/50721 ER -
