Abstract:

Dynamic plane strain thermomechanical deformations of a thermally softening viscoplastic body subjected to compressive loads on the top and bottom faces are studied with objective of exploring the initiation and development of a shear band from the site of the defect. It is found that, irrespective of the way the material inhomogeneity is modeled, a shear band initiates from the site of the defect and propagates in the direction of maximum shearing.
