| Abstract: | In this paper,the finite torsion of a viscoelastic circular cylinder is studied by means of sn ap-proximation theory of finite linear viscoelasticity.Numerical solutions are given by using the ex-perimental datas on styrene butadience rubber.The expressions of stresses of the circular cvlin-der are obtained.The phenomenon of stress relaxation and other nonlinear effects of the cylinderare discussed. |
