An approach for fatigue crack propagation analysis by smoothed particle hydrodynamics method

An approach for fatigue crack propagation analysis by smoothed particle hydrodynamics method In this study, a smoothed particle hydrodynamics (SPH) method for analyzing fatigue crack propagation was developed. In the simulation program, a crack is modeled to propagate virtually in particles based on the linear fracture mechanics and the Paris-Erdogan Law. This is realized by removal of one particle per analysis cycle. The SPH simulation in the case of the half elliptical surface crack propagation has given a smooth crack shape history, which is similar to the fatigue test result. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Strength, Fracture and Complexity iospress

Abstract

In this study, a smoothed particle hydrodynamics (SPH) method for analyzing fatigue crack propagation was developed. In the simulation program, a crack is modeled to propagate virtually in particles based on the linear fracture mechanics and the Paris-Erdogan Law. This is realized by removal of one particle per analysis cycle. The SPH simulation in the case of the half elliptical surface crack propagation has given a smooth crack shape history, which is similar to the fatigue test result.
