用弹塑性有限元方法,以裂尖张开角参数为断裂准则分析了双轴载荷比对含裂纹加劲曲板中扩展裂纹尖端应力场、塑性区形状和尺寸,加劲桁条中应力分布及加劲曲板结构剩余强度的影响。发现双轴载荷比的增大使曲板的曲率增大,明显改变了扩展裂尖处应力分布、塑性区的形状和尺寸,虽可提高起裂名义应力,但却使整个结构的剩余强度明显降低。加劲曲板结构的最终破坏是因蒙皮中裂纹快速失稳扩展所致,而这种失稳扩展是由加劲曲板内侧裂尖局部处材料的塑性垮损开始的。

The problem of axisymmetric buckling and postbuckling of a circular thinfilm delamination bridged by throughthickness fiber tows in 3D composites is presented. An iterative procedure based on Taylor’s series expansion is used to generate a family of nondimensionalized postbuckling solutions of the above problem by von Karman’s nonlinear plate theory. Attention is focused, herein, on effects of the bridge force of throughthickness fibers on buckling and postbuckling behavior of the delamination. It is found that fiber bridge not only increases the ability of resisting delamination buckling and postbuckling, but also brings on the jump of the delamination deflection mode during the postbuckling phase. Consequently the behavior of the composite structure with delamination is greatly improved, such as increasing the residual strength and prolonging the service life.

利用vonKarman非线性薄板理论,借助Taylor级数展开方法,求解了3D复合材料中圆形薄膜脱层的屈曲和后屈曲问题.其中着重分析了横向纤维搭桥约束作用对脱层屈曲性能的影响.大量的计算和分析发现,与无搭桥脱层的特征不同,纤维搭桥不仅起到了抑制脱层演化发展的作用,而且也会导致脱层屈曲模态的突变,从而大大改善了结构性能,提高了结构的剩余强度和使用寿命.
