, by contrast, solves the equations of motion without matrix inversion, marching forward in time using a central difference scheme. The method is conditionally stable—the critical time step must be smaller than the smallest wave travel time across any element in the mesh—making it ideal for wave propagation problems, high-speed impact events, and highly nonlinear analyses involving material failure or fragmentation. For large-scale SSI problems with relatively short dynamic response times, the explicit method offers superior computational efficiency. it travels through soil.
An earthquake doesn't hit a building in a vacuum; it travels through soil.
