Our group has been studying the vibro-acoustics, ultrasonics, biomechanics and bioengineering by computational modeling and simulation since 1989. Here a short introduction is given to what we have done in acoustics and biomechanics, mainly focusing on how to apply modeling and simulation techniques to solve real engineering problems. Examples include the design and virtual evaluation of ventilation windows, numerical method development using guided waves for defect detection, and simulation based design of vascular stents. Some recent efforts in using metamaterials which including auxetic and origami structures for developing such devices are also discussed.

Key words: Vibroacoustics, Structural Health Monitoring, Biomechanics, Device mechanics, Metamaterials

Dr. Cui Fangsen received his B. S. and M. Eng. degrees from Engineering Mechanics  Department at Xi'an Jiaotong University in 1984 and 1989, respectively. He completed his PhD work from Mechanical Department of National University of Singapore (NUS) in 1998, and then joined the Institute of High Performance Computing, A*STAR as a research engineer. He is now a Senior Scientist and a team leader in acoustics and biomechanics computing. His research interests lie primarily in developing acoustic devices (muffler, ventilation window, noise barrier, structural health monitoring, etc) and biomedical devices (vascular stents, artificial joints, etc).   He is the principal investigator or co-investigator of many grants with total support around 10 millions (in Singapore Dollar). He has several PCT patents and published many papers in both prestigious vibroacoustic journals and biomedical journals.

Dr Cui is a General Council Member of International Association for Computational Mechanics (IACM, from 2012), Executive Council Member of Asia-Pacific Association for Computational Mechanics (APACM, from 2018), Vice president of International Chinese Association for Computational Mechanics (ICACM, from 2016), and the president of Singapore Association for Computational Mechanics (SACM, from 2017).
