有界圆柱体的动应力和动应力集中现象

DYNAMIC STRESSES AND DYNAMIC STRESS-FOCUS PHENOMENON IN A SOLID CYLINDER

本文利用特征函数方法求解了有界圆柱体在冲击载荷作用下的动应力响应历程和分布规律。在求解过程中，对求解此类问题的早期工作中所存在的错误进行了修正。通过一个实例计算，表明本文求解方法是正确的，并给出了一些有实际意义的结果。

This paper solves the histories and distributions of dynamic stresses in finite solid cylinder under shocking load by using eigenfunction method. In solving process, We comment on the mis take invilved in some previous works for this problem, Throuhg a real example, the solving method in the papers is shown as correct and some intersting results are obtained.
