Title: Finite Element Analysis Method for the Stress Intensity Factor of Surface Cracks
Abstract: Investigates the modeling methods for three dimensional surface crack problems.Based on finite element method,1/4-point displacement method and J-integral method are used to calculate the stress intensity factors along the entire crack front.Several meshing cases are studied.It is shown that,when using 1/4-point displacement method,the stress intensity factor results are sensitive to the crack front region size and non-sensitive to the mesh size.For J-integral method,the results are non-sensitive to both the mesh size and mesh style,and suitable to calculate the stress intensity factor of complex structures.
