Research on Fatigue Crack Propagation of 304 Austenitic Stainless Steel Based on XFEM and CZM [PDF]

Metals, 2020
The fatigue crack propagation of 304 austenitic stainless steel was studied both by experiments and numerical simulations. Two methods were applied to simulate the crack propagation: the extended finite element method (XFEM) and the cohesive zone model ...

CZM Applications of Argus Coastal Imaging at the Gold Coast, Australia [PDF]

Journal of Coastal Research, 2004
Abstract A video-based ARGUS coastal imaging system is being used at the northern Gold Coast, Australia to monitor and quantify the regional-scale coastal response to sand nourishment and construction of the world-first Gold Coast artificial (surfing) reef. This automated monitoring system is used to obtain hourly daylight images from four cameras that

Study on the Degradation of SOFC Anodes Induced by Chemical and Electrochemical Sintering Using EIS and µ-CT

Applied Sciences, 2023
The goal of the present study was to quantify degradation phenomena on anodes that can be attributed to chemical (thermal) and/or electrochemical sintering, to find out the underlying mechanisms, and to propose countermeasures. The samples were thermally

Use of combined CZM and XFEM techniques for the patch shape performance analysis on the behavior of a 2024-T3 Aluminum structure reinforced with a composite patch

Fracture and Structural Integrity, 2022
The presence of a geometric discontinuity such as a crack or a notch can cause the failure of a structure during its use. Under various mechanical or thermal stresses, a high concentration of stresses can take place at the level of these discontinuities,
