ANSYS finite element analysis (FEA) was used to determine the SIFs along the crack front of surface cracks embedded in the solid circular bars. 20-node isoparametric singular elements were used around the crack tip by shifting the mid-side node 1/4-position close to a crack tip. Different crack aspect ratio, a/b were used ranging between 0.0 to 1.2 and relative crack depth, a/D were ranged between 0.1 to 0.6. Mode I SIF, K I obtained under bending moment was used to validate the proposed model and it was assumed this proposed model validated for analyzing mode III problems. It was found that, the mode II SIF, FII and mode III SIF, FIII were dependent on the crack geometries and the sites of crack growth were also dependent on a/b and a/D. 2014-06-09T08:44:14Z 2014-06-09T08:44:14Z 2011-02 Article Advanced Materials Research, vol. 214, 2011, pages 192-196 1022-6680 (Print) 1662-8985 (Online) http://www.scientific.net/AMR.214.192 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35210 10.4028/www.scientific.net/AMR.214.192 en Trans Tech Publications
