In this talk, the design, modeling, and simulation on acoustics (vibration and noise, ultrasonic waves non-destructive testing, and structural health monitoring) and biomedical devices (vascular stents) is discussed. It is demonstrated that modeling and simulation plays a pivotal role for successful completion of projects. First an overview is given to the topics. The latter segment of the talk delves into a specialized exploration of ultrasonic waves. Specifically, it delves into the Rayleigh waves and the zero-group-velocity (ZGV) mode waves, and how to combine it with the sensor technology for effective defect detection. The application of machine learning (ML) with ultrasonic waves is also discussed. Finally, the development of a novel stent-graft, incorporating both computational structural analysis and fluid dynamics analysis, is presented.
