Abstract

This paper presents three-dimensional (3D) finite element solution on multiple surface cracks. The cracks on solid cylinder are similar in sizes, parallel each other, assumed to grow in semi-elliptical shape and subjected to remotely tension loading (mode I). A wide range of parametric study involving crack depth ratios ( 0.1≤a/D≤0.4), crack aspect ratios (0.2≤a/b≤1.2), normalized coordinates on crack front (0.0≤x/h≤0.93) and inter-crack distance ratios (0.005≤c/l≤0.32) are considered for numerical estimation of stress intensity factors (SIFs) along crack front. For multiple surface cracks under axial loading, the stress intensity factors along crack front decreased when c/l decreased. When multiple cracks approach one another, the stress intensity changes due to interaction of the stress field. The results show that it produces a stress shielding effects.
