Stress cracking resistance
Failure due to stress cracking (ESC = environmental stress cracking) is the most common failure cause with about 25 % of all failures for plastic components. Failure times can be significantly reduced by simultaneous influence of stresses (external or internal) and media that trigger stress cracking.
Besides the evaluation of stress cracking resistance using standard test methods, we develop accelerated test methods for faster lifetime predictions.
Special issues are:
- Investigation of slow crack growth in polyolefins
- Influence of different media, testing conditions and internal stresses on stress cracking resistance
- Crack detection using non-destructive testing methods
