Numerical Methods of Pressure-Impulse Diagrams for Damages of Plates Under Blast Loads

The different damage levels of targets can be expressed by different P-I diagrams.P-I diagrams,which are very important in the estimation of the blasting effect on targets,also provide a basis for the design of protective structures.Targets can be represented by metal plates with a certain thickness,and with the reflected parameters,the reflected pressure-impulse criterion can be used to assess the damage caused by the blast.This paper combines...
