Experimental stress determination of blunt notches under combinations of modes I and II loading
Engineering Structures(2023)
Abstract
•DIC method is utilized to determine the stress field around blunt notches.•A variety of notch geometries including U, VO, and Keyhole is included.•Different spectrums of mixed-mode loading using the BD test are investigated.•The effect of HOTs on the stress field of blunt notched components is investigated.
