Conventional design,ndards are not being used. In this chapter, I shall attempt to describe what seems to me to be the general methodology adopted, and note variations from it as the occasion requires. In the first instance it is advantageous to concentrate exclusively on stress-rupture phenomena. Then design involving

The factor of safety: stress-rupture modes,tions will have to be made to remove ill-defined parameters before any quantification can be undertaken. Thus it will be assumed that a single role factor is to be evaluated. In doing so we are not restricting the approach in any way. Secondary functions of the factor can be introduced into the load

Wear and wear-out,o failure. In spite of this, a common approach to all wear mechanisms is highly desirable, otherwise design methodology becomes a never-ending topic. A common approach is certainly the target of this book. In principle this is readily achieved, because the methodology of stress-rupture can be carrie

A design methodology,is of doubtful advantage for the much simpler stress-rupture mechanisms. The reason for this must be fully recognised. A lower level of design reliability is acceptable for wear because it can be countered by maintenance (when properly carried out), while maintenance can have no effect at all on the

做方舟

A final review,no attempt has been made to cover the epiphenomenological statistical aspects of design applied to systems, which at present is possibly the most widely practised form of statistical design. There are two reasons for this. First, the basic principles are well established, and have been covered adequ
