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。
Applying the slip-line field theory derived from the Tresca yielding condition and the Haar-Von Karman complete plasticity hypothesis, this paper presents a more simple and effective solution to the plastic deformation problem than the Z.Mroz slip-line field method The method is applied to solve the problem of the ultimate load of some cylindrical members with various shapes of circular incisions.
