We describe the first two dimensional (2D) model to reproduce subharmonic generation at closed cracks using damped double nodes (DDN). Numerical simulation using finite difference time domain (FDTD) method was performed using DDN. We verify transparency of low amplitude wave to closed cracks and typical stress divergence at crack tip produced by large amplitude wave.
