Explicit methods are . They are only stable if the time step size ($\Delta t$) is smaller than the time it takes for a stress wave to travel across the smallest element in the mesh. This is defined by the Courant-Friedrichs-Lewy (CFL) criterion:
It is computationally expensive. It requires meticulous mesh quality. But when you watch a simulation of a crumple zone absorbing kinetic energy or a turbine blade surviving a bird strike, you realize the power of moving beyond the steady state. explicit dynamics
Used for processes that are technically static but involve severe nonlinearity (buckling, complex contact) that prevents Implicit solvers from converging. Explicit methods are

Successful implementation requires strict adherence to mesh quality, rigorous energy balance checking, and an understanding of the trade-offs involved in mass scaling. As computing power increases, Explicit Dynamics is increasingly being used for design optimization in addition to validation.
