This study presents a method to develop an analytical aspect for J-integral prediction of surface crack in round bars under combined mode I loading. This technique is based on the local limit load approach considering a plastic deformation across the crack ligament. Then, the developed limit load is then combined with the reference stress method to predict J-integral along the crack front of surface crack in cylindrical bars.
