http://www.iotword.com/5488.html Webthe constrained-based methods might be more stable, where by default, the slave nodes are first projected onto the master surface. Over- or underestimated penalty forces can also occur in the global contact condition between the THUMS model and the vehicle, where entirely different materials interact (Fig. 8 - right). The materials of the vehicle are usually …
