Abstract

Metallic materials such as iron, steel, and aluminum and polymeric materials such as resins, fibers, and rubber, which are indispensable for our daily life, are developed for application under severe environment and weight reduction of structures. To enhance formability and reliability of the advanced materials, we are expecting the construction of theoretical models that can understand the mechanical properties based on the microscopic behavior of the material and express the deformation behavior of the advanced material. In this study, complex behavior of materials is calculated using “Multiscale Plasticity” that simultaneously express phenomena of different scales such as an atomic scale on crystal structures and a continuum scale on macroscopic structures. Furthermore, we aim to unite the data obtained by experiment with computational research and to create new predictions.


Biography

Dr. Yoshiteru Aoyagi is an associate professor of Department of Finemechanics at Tohoku University. He received his Ph.D. degree (2006) from Keio University, Japan. From 2006 to 2009, he was an assistant professor at the Department of Mechanical Engineering at Keio University. In 2009, he moved to Nuclear Science and Engineering Directorate at Japan Atomic Energy Agency (JAEA) as a researcher. In 2012, he moved to Tohoku University as an associate professor. His areas of specialty are simulation and modeling of plasticity on advanced materials such as ultrafine-grained metals and fiber reinforced plastics.
