Assessment of Damage Tolerance Requirements and Analysis - Task 1 report. Volume 2. Analytical Methods

Abstract

The stress intensity factor and stress severity factor for typical airframe structures have been formulated using the compounded solution method. Two-dimensional and three-dimensional finite element analysis were performed to validate or obtain some of the factors. Two damage tolerance analysis methods have been developed based upon the stress intensity factor and stress severity factor. The first method is based on crack growth only. The second method is based on the combined crack growth and initiation. The strain energy density is proposed as the governing parameter of fatigue crack initiation.
