The use of composite parts to replace their metal analogues for the structural components within the bodies of transport vehicles offers many positive outcomes. It reduces the cost of production, the weight of the piece and hence the overall energy consumption. However, because of their inherent differences metals and composite materials exhibit very different modes of failure. Fig. 16.1 shows a typical comparison of the fatigue damage of composites and metals over time. For metals, a predominant single crack is the most common failure mechanism. On the other hand, in composite...
