The notched brass couplers will be placed in a 50 kip servohydraulic testing frame to be loaded to given stress levels to determine fatigue life. The fracture surface of each coupler will be examined using low magnification (10x) microscopy in order to develop a correlation between fatigue zone and brittle fracture zone as a function of stress level and fatigue life.
