Failure under static or dynamic loading conditions is a major concern in the application of polymers in load-bearing components: it is not the question whether it will fail, but rather on what time-scale. It is imperative that the ability to estimate the lifetime of polymer components under design-load specifications is essential in their design and optimization. With the increasing social demand for durable products with long service life, and a gradual shift to more critical applications, e.g. involving high loads and temperatures (e.g. under-hood automotive applications, domestic hot water systems), the need for such predictive methods is even more vital.

 

In the absence of reliable models, one is left with no other option than to revert to prototyping and full-product tests. Unfortunately, such trial and error approaches are time-consuming, costly and hamper flexible product development.

 

In my presentation I will give an overview of current options for modelling and accelerated characterization protocols concerning the long-term performance of load-bearing polymer systems.
