The Study of Large Plastic Deformation and Fracture of Plates by Blast of Explosives in the Tubes

摘要

Experimental studies and calculations of large plastic deformations and fracture of the aluminum alloy plates of different thickness by the shock waves of blasts of powerful explosives in tubes of different lengths and diameters were carried out. The deformations the plates were investigated with a single and consistent impact loading by shock waves. Parameters of shock waves and loads on the plates in the tubes were measured and method of their calculation was worked. The empirical dependences of the maximum residual deflections and increment area of the plates depending on the load pulse parameters and the plates were obtained. Dynamic strength of the aluminum alloy was defined.
