ELASTIC/VISCOPLASTIC SOLUTION OF TWISTY COLUMNS BY MEANS OF LAPLACE FUNCTIONAL TRANSFORMAIIONS
弹／粘塑性柱体扭转问题的函数Laplace变换解

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.
