Effect of through Crack Size on Strength of Shell Structures

Abstract

The analysis of numerous cases of failure in shell structures has shown it occurs at stresses lower than the design stresses. The origin of these failures has been attributable to flaws or cracks. To determine which size of crack is admissible, one must study how the structural strength is affected by cracks. In this paper, the analysis is done using a finite-element program developed by the authors. The stress intensity factor,
