... manufacturers. Tensile test data indicated that the companion hooks were significantly different from hooks made by other manufacturers. The hooks broke into several pieces and failed with little or no plastic deformation, while hooks made by other manufacturers plastically deformed and did not break during...

... Abstract Wear, a form of surface deterioration, is a factor in a majority of component failures. This article is primarily concerned with abrasive wear mechanisms such as plastic deformation, cutting, and fragmentation which, at their core, stem from a difference in hardness between contacting...

.... It is believed that failure was caused by the lack of a screw in the ninth hole. Evidence is also presented which indicates that the device was bent prior to insertion, and the local plastic deformation may have caused structural changes leading to premature crack initiation. Compression hip screws...

... was occasionally used in the system. Analysis (visual inspection and 250x micrograph) supported the conclusions that failure of the latch was caused by plastic deformation from extensive loss of metal by galvanic corrosion and the sudden loading related to the tripping of the valve. Failure in some regions...
