报告人简介(英文)：Dr. Zhou is currently an assistant professor in the Department of Joining Design and Structuring at JWRI. His research topic is assessing the fatigue performances of welded joints from both microscopic and macroscopic perspectives. He received his PhD from The University of Tokyo, Japan, where his research focused on fatigue fracture. In the past three years, he investigated the effect of grain boundaries on fatigue crack growth, demonstrated the applicability of the multiscale model to macro-crack problems, and proposed the bridging strategy between micro and macro cracks. This multiscale fatigue model was successfully applied to structural components and material design. Now, he continues his research on predicting multiscale fatigue behaviour, with a shift in focus from simple base metals to complex welded joints and additive manufacturing materials considering the material and structural inhomogeneities.
