Preliminary study of using kerf as an alternative to crack interactions in multiple edge cracks based on non-uniform stress distribution
Ahmad Faizal, Annuar; Muhamad Saisuldin, Abdul Manan; Haftirman; Ahmad Nabil, Mohd Khalil (Praise Worthy Prize, 2014)Multiple cracks with different or similar geometries that coexist on the same plane will affect its neighbouring counterpart’s Stress Intensity Factor (SIF) value due to interaction effect. The interaction effect is much ...
