An integral formulation of the elastodynamic equations is presented and discretized to develope a numerical solution procedure. Constant space and linear time dependent interpolation functions are implemented. The expressions obtained, the boundary element equations can be solved using a time-stepping scheme. An example is given for comparison with known solutions.
