Abstract: Single-edged notched tension (SENT) specimen is used to study the fatigue crack growth rate (FCGR) behavior of AISI 50100 steel using MTS 810. Calibration tests are run to get plots of crack mouth opening displacement (CMOD) vs. Load and CMOD vs. Crack length to width ratio with the known crack lengths. FCGR of welded and un-welded specimens are plotted against stress intensity range to show the effect of welding on fatigue crack growth rate of AISI 50100 steel, initial results of the experimentation are presented.
