These crossing fibers put traction on the crack surface and the traction depends nonlinearly on the crack opening. In order to model this traction on the crack surface I would like to be able to make a nonlinear displacement/force law in the x,y and z direction, respectively, without any dependency between the three displacement/force laws. </p> <p>Does anyone know what can be done in Ansys to do this? </p> <p>Thanks in advance</p> <p>Regards Brian </p>
