Forming sheet metals under blast loading or the explosive forming technique has many advantages for productions, but it is restricted due to its accuracy. This paper introduces a novel theoretical-empirical study for explosive sheet metal forming based on the simple plasticity principles. It provides a method of producing the sheet metal cone parts forming under blast loading, including an analytical model and experimental validation. Firstly, a theoretical-empirical model for cone forming based on underwater explosion employing the impulse method is developed. The model on the whole revealed the relationships among the geometrical parameters of forming a process that is very useful to predict the certain explosive mass for complete forming a cone part. Afterward, a series of experiments are conducted to validate the developed model and also for the required modification in the solution. Comparing the theoretical-empirical solution and experimental results, the ability of the presented model for estimation of the explosive mass is demonstrated. Experimental results show that the theoretical model matched the experiments well.

“…Shaped charges have received considerable international attention in recent years and are effectively used in military and civilian fields [1][2][3][4][5][6][7][8][9][10][11][12]. Molinari [1] used a finite-element Lagrangian code to simulate a process from jet formation to its penetration of a plate.…”

“…However, computational difficulties can be caused by element distortion when traditional mesh-based methods are used to deal with nonlinear problems of high-speed impact. A meshless smoothed particle hydrodynamics (SPH) method [4][5][6][7][8][9][10] can overcome limitations related to the distorted mesh caused by large deformation. Feng et al [7] applied the SPH method to study explosion-driven metal deformation and jet formation as well as penetrating effects.…”
