This work concerns the transient response in elastodynamic quarter plane problems with mixed boundary conditions. Two dimensional elastodynamic equations are solved analytically applying integral transformations and Cagniard-de Hoop method. The plots of displacements in response to impulse function are obtained by numerical integration.
