Multiple physical modeling for damage mechanism of high energy laser weapon

The research on damage mechanism of high energy laser weapon is the basis for evaluating the damage effect. Based on the damage mechanism of the high-energy laser weapon, effect of thermal damage, mechanical damage and radiation damage by laser irradiation were investigated. Considering the surface state of different materials under laser irradiation, two models as steady state and unsteady state were established respectively. Moreover, numerical simulation was performed to evaluate the influence of tangential flow. In addition, the energy utilization efficiency of laser irradiation was discussed, and the effect of different materials on the laser protection was also compared. The results of the current can provide theoretical basis for laser damage assessment.
