Modeling of laser heating of bi-layered microdomain using the general boundary element method

Heat transfer processes occurring in 3D bi-layered microdomain subjected to the ultra-short laser pulse are considered. The problem is described by the system of two dual-phase lag equations supplemented by appropriate boundary and initial conditions. The ideal contact condition at the interface between the layers in the case of the dual-phase lag model is formulated in a different way than in the macroscopic Fourier one. To solve the problem the general boundary element method is proposed. In the final part of the paper the examples of computations are presented, and the conclusions are formulated.
