Abstract or Summary
  • The formation of shear bands in isotropic micropolar elastic materials is considered in this thesis. The investigation concerns localized deformation fields due to jumps of second-order gradients of displacement across a standing singular surface. Such a standing surface gives rise to a shear band. The condition for the existence of a shear band is obtained in terms of an appropriate acoustic tensor for the micropolar continuum. The behavior of the inclination angle of the shear band is examined under varied loading conditions. Numerical calculations are presented for a micropolar elastic solid in the two cases, of uniaxial tension, and of tension of a thin plate.
