Abstract:
The classical problem of torsion of a straight rod which cross-section is limited by a convex contour is solved. It is assumed that the plastic domain covers entirely the external boundary. The conservation laws are used to solve the problem. For a piecewise smooth boundary a solution in quadrature is found. Programs which permit construction of plastic and elastic regions in a twisted rod to any precision are written. Their testing for the known solutions indicates the coincidence of results.
Keywords:conservation law, exact solution, unknown boundary, the problem of torsion of a straight rod.
