Reliabilty Through Statistical Material Property Definition
Reliability can be improved by the careful definition of the mechanical properties of engineering materials. Methods to define these properties for design functions by the use of statistics and probability concepts are presented. In addition, methods will be presented for quantitatively measuring the effects of specification screening on the improved properties of the acceptable materials. By selection of the proper design allowables based on required failure rate, reliability can be designed into components using the techniques discussed and illustrated.
