Abstract: Periodic structures have interesting acoustic and vibration properties making them suitable for a wide variety of applications. In a periodic structure, the number of frequencies for each wavevector depends on the ...

Abstract: Electromechanical actuators exploit the Lorentz force law to convert electrical energy into rotational or linear mechanical energy. In these electromagnetically induced motions, the electrical current flows through wires ...

Abstract: Resonant ultrasound spectroscopy (RUS) is an experimental method to measure elastic and anelastic properties of materials. The RUS experiment is conducted by exciting a specimen with a simple geometry and measuring resonant ...

Abstract: Resonance ultrasound spectroscopy (RUS) is a nondestructive technique for evaluating elastic and an-elastic material properties. The frequencies of free vibrations for a carefully crafted sample are measured, and material ...
