摘要
在应力Laplace变换分析粘塑性轴对称问题基础上,对弹性-弹/粘塑性圆柱体扭转全过程进行分析,根据柱体扭转的应力分布,构造应力函数与位移函数,并对函数进行Laplace变换。相应求出圆柱体、空心圆柱体的Laplace变换解,以及圆柱体的弹性-粘塑性交界线值。
By means of Laplace transformation,the whole process of the twisting ofelastic/viscoplastic columns are solved in this paper.In considering the distribution of thestresses in the column,we construct a stress function and a displacement function and thenuse Laplace transformation.The solutions cylinder and a cylinder with a hole are obtained.
