| Tóm tắt | Thin films constitute key elements in various multilayer electronic and optical devices such as integrated circuits, magnetic storage media and thermal sensing. One of the important parameters controlling the thermomechanical integrity and reliability of thin film systems is interface adhesion, which is characterized by two independent parameters: the interface strength and the interface fracture toughness. Laser-induced spallation methods have been developed to quantify these thin film interface adhesion parameters. The research presented in this work also involves developing new numerical methods to analyse a dynamic adhesion experiment that uses laser-induced stress wave to achieve a stable interfacial crack growth. Direct comparison between computational and experimental results is made to extract the interfacial fracture toughness.
Speaker bio: Dr Phuong Tran is an Associate Professor in the School of Engineering, and member of the Centre for Additive Manufacturing (3D Printing), School of Engineering, RMIT University. His research interests lie at the interface between solid mechanics and materials engineering with the aim to develop novel materials that exhibit paradigm-shifting properties for extreme loading protection that can impact the general field of infrastructure and lightweight structural materials. Dr Tran received his Ph.D. in Theoretical & Applied Mechanics from University of Illinois, Urbana Champaign, USA and then worked as a postdoctoral researcher at Northwestern University, USA. Dr Tran has supervised over 20 Ph.D. students with 12 completions. He has published four book chapters and over 150 refereed journal articles. Dr Tran and his Ph.D. students were awarded a number of best paper prizes for their research on computational mechanics and shock & impact on structures. |
