Torsion of anisotropic and inhomogeneous prismatic rods with a rectangular cross section

摘要

The limiting state of prismatic rods made of anisotropic material under torsion under the condition of translational plasticity is investigated.The rod of heterogeneous material is represented by a composite rod,when different plasticity conditions are true in different parts of the rod.Basic relations are determined by the method of characteristics.A field of characteristics of the basic relations for anisotropic and composite rods is constructed under the condition of translational plasticity,relations are obtained by characteristics,a tension break lines are found.
