This seminar presents a detailed thermomechanical comparison between fatigue pre-cracked and sharp-notched Ti-6Al-4V specimens under dynamic mode II loading. Using a single-point impact experiment, the response of these specimens was investigated through synchronized high-speed thermal and visual imaging. Frictional heating was isolated by comparing the thermal energy in fatigue pre-cracked specimens, which exhibited crack flank friction, to that of notched specimens with negligible friction.
