摘要: 给出含非对称裂纹铆接加筋壁板的应力强度因子计算方程,考虑了两种裂纹位置,即裂纹在桁条两边非对称地扩展情况和裂纹在两桁条之间非对称地扩展情况。该计算方程同样适用于铆钉均布桁条对称裂纹情况。

Abstract: The stress intensity factor(SIF) in the sheet of the riveted and uniformly spaced stringers with asymmetric carcks is calculated with regard to the following two types of crack location: craccks growing asymmetrically at two sides of the stringers or cracks growing asymmetrically between the stringers, similarly this calculation fits for the symmetric cracks ofsuch type.
