Method for calculating through-the-thickness, three-dimensional (3-D) crack-opening behavior in standard fatigue-crack-growth test specimens devised. Involves determination of crack-opening loads from crack-propagation data and finite-element analyses. In method, one considers variation in rate of crack growth along crack front, relationship between rate of crack growth and effective stress intensity factor, and variation in three-dimensional stress-intensity factor along crack front. Developed to provide simpler means for obtaining fatigue-crack-opening behavior loads.
