Dynamic Shear Testing

At DyMaLab a novel shear specimen geometry was developed that can be used for static and dynamic tests. The main objectives during the design of the shear specimen were to obtain a homogeneous stress state with low stress triaxiality in the zone of the specimen subjected to shear and to be suited for dynamic testing. Additionally, avoiding premature specimen failure due to edge effects was aimed at.
