Weight function method and stress intensity factor for two unsymmetric through-thickness and quarter-elliptical corner cracks at circular hole
Engineering Fracture Mechanics（2022）
摘要
•Accurate and wide-range weight functions of two hole-edge cracks are derived.•A 3D weight function method for two unsymmetrical corner cracks is established.•It is accurate and much faster than FEM for SIF calculation.
