Simulation of nonlinear ultrasonic waves in anisotropic materials using convolution quadrature time-domain boundary element method

ABSTRACT

In the stick contact state, the relative velocity of the horizontal crack opening displacement φ1 ( )x,t and the vertical crack opening displacement φ2 ( ),x t must be zero as shown in the lower left of Figure 2.
