轴对称问题的滑移线场图解法

Graphical Method of Slip Line Field in Axial Symmetry Problems

应用由Tresca屈服条件和Haar-Von Karman完全塑性假设,推导出的轴对称问题滑移线场理论,本文提出了较Z.Mroz滑移线场图解法更加简便有效的直接作图求解塑性变形问题的方法,并用此方法求解了一些具有各种形状环形切口的圆柱构件拉伸的极限载荷问题。

Using the theory of slip line field in axial symmetry problem deduced through the Tresca yield condition and the Haar-Von Kar man complete plasticity asumption, the authors of this paper have given a direct graphical methdd solving plastic deformation problems which is simpler, more convenient and more effective than Z. Mroz's graphical method of slip line field. Some limit load problems of cylinder components with ring notch of various shapes under tension have been solved by the direct graphical method.
