A common vibration energy scavenging structure is a cantilever beam with piezoelectric surface layers. Increasing the energy harvesting efficiency of these devices is based on the stress distribution on the beam surface. Calculating stress distributi

Single degree-of-freedom (SDOF) resonators are commonly used in modeling of dynamical systems. The SDOF resonator parameter extraction methods utilize the complex form of the frequency response function (FRF), which may not be available. The half-pow

A linear dashpot is a common equipment used in shock and vibration isolation. It has been shown theoretically that the vibration isolation performance can be significantly improved by a damping profile that depends on the piston relative position. In
