Shape Memory Composite Stent Analysis through Finite Element

Mr. Kim Youngbin, a doctoral candidate in the research team led by Professor Jeon Heungjae in the Department of Mechanical Engineering, simulated the behavior of shape memory composite stents using finite element analysis. The research team investigated the behavior of a composite material incorporating polycaprolactone, a material with shape memory properties, and iron(III) oxide (Fe3O4) added to enhance magnetic responsiveness and stiffness. By applying environmental conditions such as heat, light, and magnetic fields, they studied the material's ability to retain its initial shape. The research findings were presented at the 2023 Fall Conference of the Korean Society for Composite Materials (November 18-20, 2023), and Mr. Kim Youngbin received the 'Best Paper Presentation Award' for this work.
