Abstract

An adiabatic shear and produced by simple shearing in a rectangular body with a notch is analyzed numerically by the finite element method, using a stress-strain curve for the adiabatic condition, which shows an instability region due to the strain softening. Formation and propagation of the shear band are investigated for different geometrical conditions and compared with the plastic deformation of a material which has no instability region. When the plastic strain near the notch tip reaches the instability strain, the shear band starts to propagate faster than the expansion of plastic deformation area in the stable hardening material and the velocity of the shear band increases acceleratedly. A width of the shear band is estimated to be about 7µm.
