![]() To reduce testing time even further, degradation tests can be conducted at elevated stresses. Degradation analysis allows users to extrapolate failure times based on the measured degradation data during the degradation test. Failure occurs when the degradation value reaches a predefined critical level. Many failure mechanisms can be directly or indirectly linked to the degradation of products. ![]() Degradation analysis is an effective reliability analysis tool for products that are associated with a measurable performance characteristic, such as the wear of brake pads, increase in vibration or the propagation of crack size. ![]() Given the fact that products today are often designed with high reliability, even accelerated life testing may not yield enough failures to estimate product reliability in a short period of time.
