Modeling of Shear Crack Propagation in Rock Masses Using Mesh-Free LRPIM by Qingbo Li, Nengxiong Xu, Weifeng Wan, Yazhe Li

“…Based on the idea of Goodman element, the elastic-plastic constitutive model of the shear cracks is derived, and the elastic-plastic analysis of shear crack propagation is realized in the local radial basis point interpolation method (LRPIM). This method avoids the loss of accuracy caused by the mesh in the analysis of fracture propagation, and the crack propagation of rock brittle material is simulated. …”

Study on Gear Tooth Crack Propagation Under the High Speed Condition based on Extended Finite Element Method by Yu Yang, Tang Jinyuan, Liu Yaoxi, Zhou Wei

“…The result shows that,the initial tooth root crack location has a great influence on the gear tooth root crack propagation,and the closer of the initial crack position to the center of the tooth groove is,the more likely it is that the rim fracture will occur（ crack propagation along radial）. The rim thickness has a great influence on the gear tooth root crack propagation,and the smaller the backup ratio is,the larger range of the initial crack location is that the rim fracture will occur. …”

Investigation on Gas-Soot Flow Distribution Characteristic of Soot Capture Process in the Wall-Flow Diesel Particulate Filter by Jianyu Li, Chunping Lu, Dongli Tan

“…The obtained results showed that the static pressure gradient along the radial distribution was greater at the inlet of the filter in capture process in the diesel particulate filter, which could easily lead to causing eventual fatigue damage due to stress concentration in the front-end of filter; moreover, the weaker the vortex strength of gas-particle formed in expansion pipe was, the better uniformity of flow velocity and soot concentration distribution were. …”
