Nonlinear Theory of Torsion of Elastic Cylinder with a Screw Dislocation
The exact solution of the problem of the large torsion and tension-compression of the solid circular cylinder with a straight screw dislocation is found. Material of the cylinder is isotropic and incompressible. Nonlinear effects due to the presence of dislocations are investigated. The impact of the dislocation on tension or compression cylinder, as well as stability under tension and torsion are investigated. The impact of the dislocation on the torsional effect of Poynting is investigated. The main results are formulated in a form admitting experimental verification.
