Abstract

In this study, J-integral expression for surface crack in solid cylindrical bars subjected to mode I loadings were developed and analysed. These expressions were used to predict J-integral along the crack front for semi-elliptical crack shaped which different in sizes and geometries. One of the advantages of these expression were to accelerate any large deformation analysis generally which takes longer computational time. Finite element analysis was used to determine a fully plastic parameter called h-function. There were two types of mode I loading used in this work namely tensile force and bending moment. Results found that J-integral predictions were succesfully conducted. However, the predictions were dependent on the crack parameters used. Increasing the crack depth, J-integral prediction required different limit load for different position along the crack front. For the case of shallow cracks, J-integral determinations can be implemented succesfully except for the case of position in the vicinity of the outer points.

Effect of Mechanical Mismatch on the Stress Intensity Factors of Inclined Cracks under Mode I Tension Loading

“…However, most of these works focused more on the normal cracks [4][5][6][7][8]. According to author's knowledge, the works on the inclined cracks embedded in dissimilar materials are difficult to find [9][10][11]. Therefore, the main objective of this paper is to analyze the behavior of inclined edge cracks in dissimilar materials subjected to mode I tension loading.…”

2D numerical modeling of crack propagation using SFEMD method of a LEHI material

“…Another type of work can also be found in crack analysis using SIF (Ismail et al, 2011;Ismail et al, 2014).…”

An Overview of Fracture Mechanics with ANSYS

“…Recently, in ANSYS version 16.0 and above the determination of SIFs using J-integral approach can be separated into different mode of failure. This can be realized using interaction integral approach [17] and other can be found in [18][19][20][21][22][23][24][25][26].…”
