The traditional approach to low-cycle fatigue (LCF) life prediction involves statistical characterization of total LCF life based on extensive testing of smooth fatigue specimens under multiple stress and temperature conditions. Total LCF life is mod

This paper describes a new stress-intensity factor (SIF) solution for an external surface crack in a sphere that expands capabilities previously available for this common pressure vessel geometry. The SIF solution employs the weight function (WF) met

This paper summarizes five years of research into new stress-intensity factor (SIF) solutions for radially advancing cracks at holes in tapered and obliquely loading lugs. To our knowledge, these solutions are the first direct methods capable of anal

Additive manufacturing processes produce components that may introduce material anomalies at any location within a component. NDE inspection can be used to find and remove anomalies that could grow to failure during the service life, but two key inpu
