The implementation of iterative outer approximation method for elasto-plastic torsion problem

This work considers the abstract problem of the elasto-plastic torsion of cylindrical bar. In the first part of the work we describe this problem using Haar-Karman principle as minimization problem over the special convex set. The second part discusses the existence, uniquess and regularity of the solution. The third part introduces the outer approximation scheme that is used for discretisation of the problem. In the last two parts we derive the implementation of the iterative algorithm in Wolfram Mathematica and we present the results of two numerical experiments.
