Abstract: In this paper, the outside singular point method with the aid of sand-heap analogy for solving elastoplastic torsion problems is proposed. This method can reduce the dimensions of the problem and effectively avoid the singularity of the solution and needs no numerical integration. It has the advantages in simplicity, efficiency and accuracy.In this paper, the outside singular point method with the aid of sand-heap analogy for solving elastoplastic torsion problems is proposed.
