Effect of Prior Quasistatic Loading on the Initiation and Growth of Dynamic Adiabatic Shear Bands

Abstract

We study the initiation and growth of adiabatic shear bands in a thin-walled steel tube deformed first quasistatically either in simple compression or simple tension or by pressure applied to the inner surface of the tube and then by equal and opposite tangential speeds applied to the end surfaces of the tube. The objective is to see how prior quasistatic deformations of the tube affect the nominal shear strain at which a shear band initiates in the tube. The first set of numerical experiments simulates tests recently conducted by Murphy who found that the nominal strain at the initiation of the shear bands decreased with an increase in the axial static compressive stress induced in the tube.
