A Laplace-domain boundary element approach for transient dynamic analysis of threedimensional
(3D) moderately thick multilayered (piecewise homogeneous) anisotropic linear
elastic composite plates is presented. The boundary element formulation is based on the system
of weakly singular displacement boundary integral equations. The spatial discretization is based
on collocation method and mixed representation of geometry and boundary functions. To obtain
time-domain solutions, the Convolution Quadrature Method with the Runge-Kutta method as an
underlying time stepping method is used as a numerical technique for inverse Laplace transform.
To improve the computational efficiency of the boundary element formulation a parallelization
scheme is implemented. Boundary element results for the test example are provided to validate
the proposed approach.
