用参变量积分法求解具有角形深切口板条纯弯曲的极限弯矩

CALCULATION ON LIMIT BENDING MOMENT OF A NOTCHED BAR DUE TO PURE BENDING WITH INTEGRATION DEPENDING ON A PARAMETER

    摘要
  • 摘要: 本文针对单边和双边具有角形深切口板条纯弯曲问题的滑移线场,在其塑性区边界滑移线上分别引进参变量s与t,然后采用参变量积分法求解出应力间断点C的位置及极限弯矩,计算结果与参考文献中传统解法的结果一致。

     

    Abstract: The paper is concerned with the slip line field for bending of a bar with the deep wedge shaped notches.Along its boundary slip line of deforming region,the parametere s and t are intruduced and then the position of disconti nuity point c and the lim it bending mo-ment were calculated using integration depending on a parameter,The results of the meth-od are the same with the conventional solution from the reference in this paper. The paper is instructed by professor Zhamg Qiang.
