Abstract
Based on the results of experiments carried out using a gas gun, data are obtained on the fracture of a VNZh-90 alloy (90% W-7% Ni-3% Fe) under a shock wave load in a pressure range of 2.5–4.0 GPa. Spall strength, which is a function of the degree of fracture and varies in a range of 1.00 to 1.25 GPa, and the nature of fracture are determined. Metallographic analysis is used to determine the damage parameter values. It is revealed that, under these conditions, the fracture comprises several stages, occurs in a (Ni-Fe) bond, and the tungsten particles do not fracture. It is shown that experimental results are in good agreement with the results of numerical calculations.
