Abstract : The solution problems in both spatial and time domains using finite element method can be based on the variational principle employing bilinear functional and adjoint formulation. This principle is extended to coupling systems in matrix vector form such as penetration dynamics. The present hyperbolic type partial differential equation of interest has two dependent and two independent variables with the coupling in the spatial domain. (Author)
