Nonlinear fitting based energetic material explosive shock wave pressure action evaluation model

Abstract There are many varieties of new developed energetic materials with different capabilities shock wave pressure action. In order to effectively evaluate the explosive damage power diverse and make evaluation model universal, TNT is used as basic material, action established in this paper based on nonlinear fitting method. Explosion tests charge quantities carried out under same test conditions, surface reflection data at proportional distances obtained. The between peak constructed explosion similarity ratio formula using function. prediction accuracy verified by typical test, proposed applied effect materials. Experimental results show that predication for evaluating method higher than 86.5067%, which can meet requirements engineering applications.
