Abstract: Radius measurement of grid-stiffened cylindrical shell is a significant task for ensuring the welding quality of launch propellant tank. With the widespread adoption of 3-D laser scanning ...

Abstract: This paper is concerned with the dynamic modelling, active vibration controller design and simulation analysis for a cylindrical shell equipped with piezoelectric sensors and actuators.

In physics, on seeking for a deeper understanding of a topic we often formulate simple questions which, though not realizable in practice, should be satisfactorily answered. For instance, what exactly ...
