Crack propagation studies using 2D automatic mesh generator

摘要

An experimental and numerical investigation of fatigue crack growth in the channelled specimens is presented. Fatigue is numericaly simulated with the finite element method in a series of calculations with changing geometry of the crack. At each crack increment, automatic mesh generator is used to cover the area under consideration with quadrilateral finite elements. Experimental and numeric results are compared, and they include fatigue crack geometry and the time dependence of crack length.
