Engineering Significance of Fatigue Thresholds and Short Fatigue Cracks for Structural Design

摘要

The significance of fatigue thresholds and short fatigue cracks for engineering structures with respect to design philosophy (safety and durability, the anticipated service loads and nondestructive inspection (NDI)) are examined. Examples for spacecraft payloads, aircraft structures (including landing gear and jet engines), offshore and littoral structures, thick-walled pressure vessels, wind turbines, power generating equipment and ship propellers are given.
