The failure of products during service can have detrimental effects from a simple decrease in performance all the way to consequences for people’s safety. Therefore, the analysis and understanding of failure of plastics parts is instrumental for product improvement, and in the prevention of failures when designing and developeing new components. Jeffrey Jansen is an expert in failure analysis and will talk in this interview with Dr. Natalie Rudolph about his work. He will answer questions about the most common failures, how one of the major causes is creep and how it can be analyzed using Dynamic Mechanical Analysis. Jeff will also give some examples that highlight his approach from problem identification to solution.
