摘要
对于纯弯曲问题,若考虑材料在应力作用下的损伤,横截面上的中性轴将偏离该截面的几何形心点,本文分析和计算了这种偏离量,给出了材料在满足幂强化塑性和蠕变条件下横截面上的应力分析。
For pure bending problem, the neutral axis of beam's cross section will drift off its primary position under the action of external force if material damage is considered. In this paper, we analyse and calculate the deviated values ,and give the stress distribution of the beam's cross section for power hardening materials and creep materials.
