In studies on stainless steel, the basic Ramberg-Osgood model can accurately represent different regions of the stress-strain curve using different values of the strain hardening exponent. However, a single strain hardening exponent value is insufficient to capture the full stress-strain curve. ...
4b). It is noteworthy to state that the change in d and s have negligible effect on fracture stress and strain for the same d/s=1 sample. Therefore, we concluded that d/s is the prominent factor in controlling the stress distribution between the pores, and thereby, the fracture stress ...

The true strain-stress curve is obtained. 测定各种工艺下的真应力-应变曲线,观察了奥氏体的动态再结晶情况,研究了变形温度与变形速率对奥氏体动态再结晶过程的影响,并结合再结晶动力学理论进行分析,发现高碳钢在1050℃下高变形速率锻造时,所得到的钢球产品具有良好的耐磨性能和抗冲击韧性,从而制定出合理的高碳钢...
Materials loaded with tension are subjected to stress concentrations at the location of material defects and abrupt changes in geometry that accelerate the strain of the material. Some materials may exhibit ductile behavior and can tolerate a certain number of defects before failure, while brittle mate...
The line 0E in the Stress-Strain curve indicates the range of elastic deformation –removal of the load at any point of this part of the curve results in return of the specimen length to its original value. The elastic behavior is characterized by the elasticity limit (stress value at the...
Therefore, our in situ strain sensor on a chip is a good platform for measuring the mechanical stress on cells. The work in this paper has made innovations in the internal environment sensing of organ-on-a-chips, which is expected to improve the precise control of the internal environment ...
1) tensile stress-strain relationship 受拉应力-应变关系 1. The variation of yield strength,ultimate strength,elastic modulus,elongation andtensile stress-strain relationshipof the HRBF500 at elevated temperatures were investigated and discussed.
The ultimate tensile strength of a material is the maximum stress on the stress-strain curve. Stress has the units of applied force per unit area the...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
