Experimental and numerical investigation of equivalent stress intensity factor models for fatigue life predictions

Abstract

Fracture of engineering components due to the fatigue is an important research area of fracture mechanics Prediction of crack length versus number of loading cycles fatigue life or crack growth curves of vital engineering components is paramount importance in the damage tolerance design and structural integrity analyses Due to the complex geometry boundary conditions and loading such predictions are to be made using the numerical methods such as finite element method etc The Paris law is...
