Fault identification in beam structures
Journal of the Franklin Institute, 1992A methodology based on the measurement of the natural frequencies of the structural system is developed for identification of the magnitude and location of the material defects and/or cracks. The numerical procedure is based on the matrix-transfer technique in which the dynamic characteristics of the system are related from one end to the other end via

On the structural dynamics of a Vlasov beam
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1983A thin-walled beam (such as the hull of a ship) may be represented as a non-uniform Vlasov beam. Such a beam may execute coupled lateral bending and twisting vibration, the nature of which is examined. Orthogonality relations are derived for a uniform Vlasov beam, which are easily adapted to a non-uniform beam that is treated as piecewise uniform ...

An actuation method by a biconcave beam structure with converse flexoelectric effect
Smart materials and structures (Print), 2019Converse flexoelectricity describes the linear relationship between an electric field gradient and the mechanical stress in dielectric materials. It is not restricted by the Curie temperature limit, does not require advanced electrical poling and a wide ...

The presentation of the finite element method starts in this chapter with the explanation of the finite element method for truss and beam systems. The concept of stiffness matrices is shown first for a simple truss element. The procedure for setting up the equations for a finite element analysis is explained exemplary for a simple truss system.

Bandwidth Increment of Piezoelectric Energy Harvester using Multi-beam Structure
2019 Devices for Integrated Circuit (DevIC), 2019Piezoelectric energy harvesters have high power density and are simpler to fabricate as compared to other low power energy harvesters. There are certain issues which need to be addressed while designing a piezoelectric energy harvester.
