An Optimum Design of Ramp Test with Stress Loading from Use Condition and Upper Bound of Stress
사용조건에서 스트레스를 가하고 스트레스한계가 있는 램프시험의 최적설계
Abstract
The common accelerated life test(ALT) consists of test methods applying a constant stress, higher than the use condition stress, to items. There we, however, situations for which a progressive stress ALT, in which the stress on a test item is continuously increased with time, Is more convenient to perform testing and simpler in analyzing data than a constant stress ALT. When a product under constant stress s follows a Weibull distribution with parameters
