Accelerated Testing of Devices on Durability and Fatigue Failure

Abstract

The problems of accelerated testing on durability are formulated and the basic definitions are given. The concept of so-called acceleration function is determined. In the case of linear model, integral function of distribution of time of failure-free operation of a device is determined on the basis of this concept. The criterions of linearity of acceleration function are formulated. The technique of accelerated testing is developed on the basis of correlation that conveys the generalized principle of Palmgren-Miner. This technique guarantees computation of reliability, when load increases permanently or stepwise.
