High cycle fatigue (HCF) of composite structures is known to exhibit self-heating coupled with stiffness degradation due to progressive damage accumulation. Recent advances have been made in correlating fatigue damage accumulation to full-field temperature fields during the HCF of composite structures. This work uses a thermal medium wave infrared camera to quantify self-heating in adhesively bonded unidirectional glass fiber reinforced polymer (UD-GFRPs) specimens under tension-tension fatigue loading.
