摘要: A description is given of a computer program for analyzing the crack propagation in cyclic loaded structures. By using equations stress intensity factors surface and embedded flaws, capability ascertaining lengthwise growth as well through thickness structure was determined. Equations used are written general form so that many other types problems, such type cracks, can be analyzed. Provisions have been made to analyze repeated blocks variable-amplitude fatigue load spectra. Additional features include variable print interval integration minimize printout run time. source listing instructions included.
