给出蒙皮带有多裂纹和蒙皮带有多裂纹且桁条也带有裂纹时应力强度因子的近似工程估算方法。

The approximate engineering approaches for stress intensity factor ( SIF ) of skin with multiple site cracks and skin and stringer with cracks are given .

对三种损伤的加筋板进行剩余强度试验，指出多裂纹尤其是桁条也带裂纹时剩余强度降低较多。

It is point out that the decrease of residual strength for multiple site cracks , particularly , for stringer with crack , are rather larger .

将桁条式y圆筒机身的中段简化为格栅状骨架结构和蒙皮结构，建立圆筒机身初始优化模型。

The middle of the stringer-style fuselage is simplified into cylinder grid frame and thin skin structures . The initial optimization model of cylindrical fuselage is established .

另外，考虑到中央翼的桁条对提高其支持刚度也会起到一定作用，因此，比较了中央翼带桁条与不带桁条两种情况下螺栓的受力特性。

Considering the effects of stringers on the stiffness of central wing , load situations of the bolts are also compared when using a central wing with and without stringers .
