Kinking of Fiber Composites

本文从理论上分析了排列纤维复合材料的压缩扭结破坏模式的各个方面。具体而言，研究将侧重于扭结带宽度与纤维直径、刚度、拉伸断裂强度、基体塑性和纤维错位的关系。该项目还将模拟扭结带形成边界、缺口和孔洞的开始和传播；以及其他复合损伤机制与扭结和扭结诱导损伤的耦合。

This research is devoted to the theoretical analysis of various aspects of the compressive kinking mode of failure in aligned- fiber composite materials. Specifically, the research will focus on the relation of width of kink bands to fiber diameter, stiffness, and tensile fracture strength, matrix plasticity, and fiber misalignment. The project will also model the initiation and propagation of kink bands form boundaries, notches and holes; and the coupling of other composite damage mechanisms with kinking an kinking induced damage.
