Study of failure probability by deterministic method reliability-strength applied to metal cables intended for off shoring

Abstract

Current developments in technology and production techniques, as well as the increase in competition, have led manufacturers to make significant progress in the quality of their products, that is to say their ability to meet the growing needs of industrial, therefore, in this process of quality improvement stands reliability. Indeed, it measures changes in the capacity of a product based on running time, possibly taking into account malfunction time.
To ensure the structural operation in optimal conditions, an analysis of its security must be combined with well-defined inspection procedures. Unfortunately many cables have never been subject to inspection or, otherwise, only very partially, due to the limitations of inspection techniques (visual, acoustic, etc.).
We will focus, in this work, to studying reliability based on the probability evaluation of instantaneous failure, why an analytical and numerical modeling will be performed to assess reliability related to probability of failure in considered case of strands connected in series - parallel and in the case of parallel - series configuration drawing on dependability computing relationships. The approach is a multi-scale approach with a total decoupling between the scale of wire and cable. The results will allow for a comparison between different models of the literature to tie the model which allows better planning maintenance.
