考虑滑移为晶体塑性的主要变形机制,推广晶体塑性理论至多晶体,建立滑移构元模型,研究了后继屈服面的移动和畸变等演化规律.基于滑移构元的潜在硬化和包氏效应的影响,后继屈服面的前端凸出,尾部缩进,呈现"前凸后扁"的特征,计算了单轴拉伸、纯扭转和拉一扭组合比例/非比例加载下的后继屈服面演化过程,与已有实验结果相符合 |

Slip is the main plastic deformation mechanism. Considering slip is the main plastic deformation mechanism, the single crystal plasticity is extended to polycry stalline. In the present study, the single crystal plasticity is extended to polycrystalline. The slip-component model is thus set up, and the tra.nslation and distortion of subsequent yield surfaces are investigated. Based on the Bauschinger effect and latent-hardening of the slip components, the su.bsequent yield surface can be described that the rear part deflates and the forward part inflates so that the subsequent yield surface has a sharp front and blunt rear. The numerical simulations are performed under uniaxial, torsional and combined axial-torsional proportional/non-proportional loading conditions. The results show that the agreement between the predictions and experiments is quite satisfactory |
