Abstract:Dissimilar material joined structures are increasingly used in the automotive industry to reduce weight in the vehicle body structure for better fuel economy. Therefore, it is necessary to reveal the fatigue damage and develop the fatigue life prediction method of dissimilar material joined structures. Unlike conventional detection methods, mechanoresponsive luminogen‐based method can directly visualize stress distribution and fatigue crack growth. An organic mechanochromic luminescence material (TPE‐4N) is th… Show more
