Abstract

Firstly, we must consider the validity of the load/strength interferance model. Essentially it is concerned with load dependence events, when loads are shared by mechanical components or in a system, no matter how complex, then there will be load dependence. Most systems of engineering interest have a mechanical element, sometimes very considerable, but the degree of load dependence varies enormously.
