A short paper by Mr. James Harter discussing the use of AFGROW to predict the crack growth life of a structure containing internal through cracks in a row of fastener holes is now available on the AFGROW web site. The paper provided details on the use of the Advanced Model Interface and provides a direct comparison with FEM results using StressCheck.
