On the experimental stand Beam of Electrons for materials Test Applications (BETA) created in the INP SB RAS, the results of heating the tungsten plate by the action of a high-speed electron beam on it were obtained. The work is devoted to the numerical implementation of the tungsten heating process model. The model takes into account the melting and evaporation of the material. The cases of influence of surface temperature inhomogeneities for the case of cracks of different geometry are considered. Currently, work on the simulation of erosion of fusion reactor wall material under high-power pulsed plasma flow is divided into two stages. The first stage is the calculation of heat sink around cracks formed under pulsed heat load. The extension of the model involves the inclusion of equations of elasticity. The second stage is the calculation of dynamics of the melt formed under pulsed heat load. The extension of the model involves the inclusion of gas dynamics equations. The results of calculations are correlated with experimental data obtained at the experimental stand of BETA in INP SB RAS.
