In the paper, an equation with two delay times (dual-phase lag Equation (DPLE)) in a version that takes into account dependence of thermophysical parameters (volumetric specific heat and thermal conductivity) on temperature is considered. particular, analysis sensitivity transient field relation to disturbances (the relaxation thermalization times) performed. The model concerns process heating ultrathin metal layer laser beam. First, case temperature-dependent presented. Next, equations respect are derived using direct method. algorithms for solving basic tasks also briefly At stage computations, authorial program based implicit scheme finite-difference method developed. final part examples numerical solutions (for layers made from gold nickel) research conducted here shows clearly visible depend, one hand, material, other intensity external source.
