Failure analysis case studies, part II: Effect of material and end-use

Some case studies are presented in this paper to show the effect of material choice and end-use on product failure. Microscopic analysis was used in these investigations to identify the fracture features. Additionally, mechanical analysis was utilized occasionally. The first case shows the importance of material choice and processing conditions on the failure of plastic products. The second case illustrates the negative effect of adverse end-use conditions on the failure of plastic parts. The third case describes the combined contribution of material choice and end-use to the plastic product failure.
