Abstract
A software package was developed to perform estimates of life to fatigue crack initiation in metals under random loading using cycle-by-cycle local stress strain analysis. This involves simulation of notch root stress-strain history under arbitrary, axial, elastic nominal stress excursions. Low cycle fatigue constants for the material and notch stress concentration factor are used as inputs for the analysis. The scftware provides a choice of five different graphical outputs. It was implemented on a PDP 11/73 using Fortran'77 and graphical output was obtained using data transfer to AutoCAD on an IBM PC compatible.
