轨道车辆SUS304不锈钢材料动态力学性能与本构模型修正
In this study, the modified maximum force criterion was used to ensure an accurate determination of the forming limit curve (FLC) for the SUS304 sheet metal. At first, the stress-strain curves according to Voce and Swift hardening models were verified using the experimental data and the stress...
The equiplastic strain surface could be represented by the quadratic form of stress when it was probed from the current center of the yield surface after cyclic preloading. Then, all the stress-strain curves of subsequent radial loading from the center were confirmed to be represented by the ...
method is used to eliminate the influence of load ratio.Finally,the finite element model of vibrating conveyor is established,the transient dynamic analysis is carried out to obtain the structural stress of vibrating groove solder joint,whose life is predicted based on the established S-N curve....
Finally, the finite element model of vibrating conveyor is established, the transient dynamic analysis is carried out to obtain the structural stress of vibrating groove solder joint, whose life is predicted based on the established S-N curve. The results show that there is no fatigu...
