In keeping with a well established precedent, ASTM Committee E-9 on Fatigue again sponsored a Symposium on Structural Fatigue in Aircraft at the Pacific Area National Meeting held in Seattle, Wash., Oct. 31–Nov. 5, 1965. Previous symposia have concentrated on the basic mechanism of fatigue, the effects of notches and other discontinuities on the fatigue behavior of materials, and, to a limited extent, the behavior of full-scale structural assemblies and components under simulated service loadings. Until relatively recently the theory of probability as applied to structural problems has been neglected by the design engineer. As a result, the “reliability engineer” has entered the void left by the structural engineer and is attempting to establish reliability standards for structures similar to those established for nickel and dime hardware items. Consequently, the structures engineer must establish his own realistic reliability standards, or unrealistic standards will be established for him.
