摘要
本文利用有限线性粘弹性理论的Ｌｉａｎｉｓ简化形式，研究了圆柱体的有限剪切。并采用丁苯橡胶的有关实验数据，进行了数值计算，给出了圆柱体的应力表达式，考察了应力松弛现象及其他的非线性效应。
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.
