Abstract

Structural components are frequently subjected to complex time histories of stress for which the prevalent mode of failure is fatigue. For reliable and cost-effective fatigue life calculations of metallic materials the systematic characterization of their fatigue behavior and the detailed understanding of basic fatigue mechanisms are of prime importance. Based on fatigue failure theories (stress-life theories such as; Goodman and Gerber, and strain-life theories such as; Morrow and SWT), this paper presents a technique to predict the fatigue life of a shell structure of different materials with application of measured variable amplitude loading. The finite element analysis technique was being used for the modeling and simulation. Numerical life prediction results of the shell materials, low and medium carbon steel (ASTM A533, AISI 1020, AISI 4340) are presented and discussed. There are many factors affecting the life predicted, a surface condition effect was shown here. Reasonable difference appears through the comparison of the above materials.
