Validation of Crack Interaction Limit Model for Parallel Edge Cracks using Two-Dimensional Finite Element Analysis

Abstract: Shielding interaction effects of two parallel edge cracks in finite thickness plates subjected to remote tension load is analyzed using a developed finite element analysis program. In the present study, the crack interaction limit is evaluated based on the fitness of service (FFS) code, and focus is given to the weak crack interaction region as the crack interval exceeds the length of cracks (b > a). Crack interaction factors are evaluated based on stress intensity factors (SIFs) for Mode I SIFs using a displa… Show more

“…The FEM is widely used in analysing nuclear power plants [3][4][5], vehicles in automation or aircrafts [6,7] and for fatigue assessment [8][9][10]. However, existing FEM is still insufficient to analyse engineering problems due limitations related to complexity of problems and computation time [11][12][13][14]. Therefore, the S-version FEM was developed to enhance the existing FEM to overcome the constraints mentioned.…”
