章節(jié)摘錄

　　glass fibcrs in a plastic binder，or inorganic crystal needles in a metal matrix（metal matrix composites）are also materials systems.In the context of failure as we have discussed，it is important to realize that failure cannot onlyoccur Within a regime（a component in a connected arrangement） but at the connectionitseU.sothe inferface is also a pad of the system and must be considered in the context of the weakest linkcorollary and Murphy's law.Failure Drevention is certainly not a hopeless issue even in very complex materials system，but it d0 esrequire a great deal of test，evaluation，and fundamental understanding of materialsbehavior under a variety of conditions.Selecting optimum conditions，underutilizing components ina sYstcm（desiCning for the weakest link and employing safety factors），introducing safety.factorsconsideration for environmental changes and even bizarre conditions of use-au contribute to Successful applications of products.One need only to take a glimpse at the technology around us to appreciate how SuccesSful We have been in designing efficient，dependable，and useful products andficture.　　……?
