Investigation of the Reliability and Longevity of Parallel Systems with Defects Using Daniels' Sequences

摘要

The Reliability and longevity of parallel systems is studied using the example of a fibrous composite material using Daniels sequences' and the Markov chain theory. The connection between the strength distribution function of the separate longitudinal elements forming the parallel system and the longevity distribution function of this system under cyclic loads is analyzed. The obtained models do not give direct coincidence with the experimental data but can be used for their nonlinear regressive analysis. Numerical experimental data processing examples are given.
