The numerical formulation used Barsoum singular finite elements to compute fracture parameters in two dimensional finite element models subjected to different crack-width ratio and cracks interval ratio. Mixed mode stress intensity factors (SIFs) of parallel edge cracks are computed in extending of FE formulation for pure Mode I formulation proposed by authors. In 2D linear elastic problem under mixed mode condition, the variation of SIF value near crack tips are discussed comprehensively. The newly finite element formulations are resulted with remarkable agreement with energy release rate based method compared to analytical solution available in the literatures. 2014-06-09T08:39:51Z 2014-06-09T08:39:51Z 2011-03 Article Applied Mechanics and Materials, vol. 52-54, 2011, pages 1326-1331 1660-9336 10.4028/www.scientific.net/AMM.52-54.1326 http://www.scientific.net/AMM.52-54.1326 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35207 en Trans Tech Publications |
