Finite element analyses including a cohesive zone model (CZM) were conducted to investigate the role of corrosion product films (CPFs) in stress corrosion cracking (SCC) for copper in an ammoniacal solution. It is found that a tensile CPF-induced stress generates near the interface between the CPF and the copper substrate at the substrate side in front of the notch tip for a U-shaped edge-notched...
For the development of ACFM intelligent and visualization inspection system, based on a large number of finite element simulation results about ACFM crack angle detection, the calculate method of ACFM crack direction by 1-D array probe is present, and the experimental test is designed and conducted with the real crack. Test results show that, when tested by the 1-D probe composed of 4 couples of detecting...
Computed on the ABAQUS finite element software, took the large group piles foundation of the Changjiang river road bridge as the research project, based on the Morison equation, using the added water mass method to consider the effects of hydrodynamic pressure, selecting three earthquake wave with different spectrum, considering dynamic nonlinear characteristics of soils and concrete, building the...
With the promotion of the electroporation therapy clinical application, how to design an electrode with a lower voltage level and distribution and high intensity electric field in order to achieve the optimal treatment of tumors. In this paper, FEMLAB finite element analysis software is used for the needle electrodes in biological tissue electroporation for electric field simulation, the simulation...
