题目：The Simulation and Role of Discontinuous Yield Behaviors of Material

作者：Hu Shao-wei

Abstract. Discontinuous yield of material as Jerky flow was explained. Then, the strain rate sensitivity (SRS) and instability criterion was given out. Some tests were carried out at constant stress rate, so Jerky flow is manifested as a discontinuity in the stress-strain curves in form of strain bursts. Finally, the dynamic behaviors of specimens during instability of thermal origin were simulated with COLSYS software, whose results are good with test ones.

Keywords: Discontinuous Yield; PLC Effect; Strain Rate Sensitivity; Calculated Simulation
