Numerical Simulation of Assessing the Damage of Explosive Blast Wave Base on Effective Target's Method

In order to reflect the overall assessment of structural damage under explosive blast wave,method for assessing the damage of Explosive Blast Wave base on Effective Target was built.By the finite element analysis software ANSYS/LS-DYNA,the numerical model was built to simulate the plastic deformation response of effective target under explosive blast wave,concluding the functional relation of effective target's deflection respectively as explosion distance and TNT equivalent,with the energy spectrum of blast wave,which effect of nature frequency on effective target's damage,the research results provided the basis and reference for damage assessment of warhead's explosive blast wave.
