adiabatic shear band
an adiabatic shear band is a narrow region, usually a few microns (micrometers) wide of intense plastic deformation that forms in high strain-rate deformations of most metals, some polymers and several other material. Because of very little time available for the heat to be conducted out of these thin regions, they are called adiabatic. The predominant mode of deformation in these regions is shearing. These bands usually precede shear fractures in ductile materials. Nucleation, coalescence and growth of voids have been observed in these severely sheared regions which eventually cause fracture of the material.
