This work is concerned with systems possessing cyclic symmetries. In particular, we concentrate on the case in which the medium possesses infinite order cyclic symmetry, while the constitutive relations have cyclic symmetry of a lower order. We investigate the interactions between modes with cyclic symmetry of order n and geometries with underlying cyclic symmetry of order M. Rayleigh's ...

This paper presents the modeling and simulation of electro-thermo-mechanical self-oscillators, an emerging type of M/NEMS-enabled timing devices in which sustaining electronic amplifiers are not required for their operation. Indeed, they realize amplification in the mechanical domain and feedback by crossing three physical domains: electrical, thermal and mechanical. In a previous work , we ...

MEMS is the leading technology which combines both electronic and mechanical devices on a single microchip. Tracing the position of the object is an important problem in engineering. This can be addressed by Gyroscopes. These sensors are used to find orientation and angular velocity. This paper focuses on 3D MEMS Piezoelectric Gyroscope. COMSOL Multiphysics® is used for designing and ...

Smart structures can sense responses and adapt to satisfy specified objectives. The objective of this study is to control the vibrations of the beam subjected to external dynamic forces. The composite beam consists of a layer of aluminum sandwiched between two layers of steel. The beam is fixed at one end and free at the other. The actuator is a piezoelectric device embedded in the aluminum ...
