The Simulation Study on Degree of Protection/Damage under Blast Loads

摘要：

　　The degree of protection/damage of the target is an important basis for the target structure design.In the military field,the target can be equivalent to a target metal plate with the certain thickness.The degree of protection can be divided through the effect of target plate under blast loads.Considering the reflected parameters,the reflected pressure-impulse criterion can be used to assess the damage caused by the blast.Through the combination of theoretical analysis and numerical simulation,the target plates pressure-impulse diagrams of different degrees are obtained.The results of the experiments and simulations are found in good agreement,which validates the numerical model.
