Physically-based modelling for sheet metal cone parts forming under blast loading

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 metal based on simple plasticity principles. It provides method of producing cone parts loading, including an analytical model and experimental validation. Firstly, underwater explosion employing impulse developed. The whole revealed relationships among geometrical parameters process that very useful predict certain mass complete part. Afterward, series experiments are conducted validate developed also required modification in solution. Comparing solution results, ability presented estimation demonstrated. Experimental results show theoretical matched well.
