摘要
本文采用P.Perzyna粘塑性本构关系式,忽略径向惯性力的影响,对受冲击扭矩作用的圆管进行了分析,导出了求解的基本方程。文中结合实例计算,给出了冪级数载荷形式的解析级数解,得到了管中应力、应变率等随时间变化的规律。
The present paper is concerned with analysis of cylindrical tube under impulsive torsion. P.Perzyna's viscoplastic constitutive equations are adopted and radial force of inertia is neglected. For example, analytic series solutions are given and stress, strain rate with respect to time are discussed.
