Abstract:

Stress screening is considered effective if and only if it leads to increased reliability. Consequently,a to-be-screened part is considered "screening-adequate" only when an effective screening test does exit to increase its reliability for its expected applications.In this paper, stress screening effectiveness criteria are discussed in terms of failure distribution and failure rate.Quantitative relationship between failure rate and failure distribution before and after screening is provided.

Key words: stress screening, effectiveness of screening, failure distribution, failure rate, reliability
