Development of plastic zones in a body with rectangular slot under the conditions of antiplane deformation

Development of Plastic Strips in the Process of Shear Deformation of a Body with Narrow Rectangular Slot

“…The crack tip is regarded as a cuspidal point. An important continuation of these investigations is connected with the study of the distributions of elastoplastic strains near rectangular slots, which turn into a classical crack in the case of infinitesimally small width [1,2].In the present work, we study the development of plastic strips from the vertices of a narrow rectangular slot under the influence of shear loads applied at a great distance from its end faces. To analyze the SSS near the vertices of the slot, we assume that it is semiinfinite.…”

Initial stage of plastic exfoliation of a rectangular inclusion under conditions of one-sided contact with a medium

“…Moreover, in contrast to a body with notches, in a body with inclusions, stress concentration is caused by not only corner points, but also points at which the contact with the medium undergoes qualitative changes. In investigating the stress-strain state of a body with an inclusion, one must foresee changes in its contact with the medium in the process of loading and, first of all, the emergence and development of plastic exfoliation on the interface.The problems of investigating the stress-strain state of a body with an inclusion that admit its plastic exfoliation remain inadequately studied [6].Let us investigate plastic exfoliation under conditions of antiplane deformation of a rigid rectangular inclusion − a ≤ x ≤ a , − b ≤ y ≤ b , − ∞ ≤ z ≤ + ∞ in an infinite ideally elastoplastic medium. Consider the case of incomplete mechanical contact of the medium and inclusion.…”
