This session will explore the various cases of plastic failure that are being seen more often in industrial, household and commercial settings. These failures can be caused by improper material specification, bad design, over loading or incorrect molding conditions. Issues such as chemical resistance, environmental deterioration, geometric sensitivity, temperature dependence and aging are at times overlooked. Various forensic techniques exist to help identify why a plastic part has failed. This knowledge will assist in allocating responsibility for its failure. The presentation will give an intriguing look at plastic failures and how one disseminates why the failure occurred.
