Control of flexural waves on a beam using distributed vibration neutralisers
This paper is concerned with the use of distributed vibration neutralisers to control the transmission of flexural waves on a beam. Of particular interest is an array of beam-like neutralisers and a continuous plate-like ...
An analytical investigation into the use of magneto-rheological elastomers to suppress flexural waves in beams
Magneto-rheological elastomers (MRE) are materials that change their stiffness and damping properties when subject to a magnetic field. They have evolved from magneto-rheological fluids which have some disadvantages, in ...
An investigation into the way in which longitudinal and flexural waves interact with corrosion-like damage
(Universidade Estadual Paulista (UNESP), 2019-01-31)
The guarantee of security in transport vehicles, buildings, bridges and critical structures is extremely important for people and the environment. Therefore, in the last decades, several Structural Health Monitoring (SHM) ...
Acoustic and bending properties in Pinus elliottii beams obtained from trees of different ages
(Springer Japan KkTokyoJapão, 2013)
Avaliação da resistência flexural de resinas acrílicas polimerizadas por micro-ondas: influência do tempo de prensagem e armazenagem pós-polimerização
(Universidade Estadual Paulista (UNESP), 2012-09-15)
Fractures of acrylic resins for denture bases are common problems in daily dental surgeon. These fractures are initiated with the formation of cracks and propagate through areas of high concentrations of stress. The ...
Experimental determination of flexural power flow in beams using a modified prony method
(Academic Press LtdLondonInglaterra, 1996)
The mechanical performance of concrete shear key for prefabricated structures
The mechanical performance of concrete connection plays an important role in the response of precast concrete structures. Unlike conventional small concrete shear key which is mainly to help with alignment at installation, ...
Theoretical Analysis and Experimental Validation of the Scholte Wave Propagation in Immersed Plates for the Characterization of Viscous Fluids
This work reports the study of an attractive interfacial wave for application in ultrasonic NDE techniques for inspection and fluid characterization. This wave, called quasi-Scholte mode, is a kind of flexural wave in a ...
Wave reflection at the end of a waveguide supported by a nonlinear spring
(European Assoc Structural Dynamics, 2014-01-01)
The way in which a nonlinear spring affects the reflection coefficients at the end of a rod and a beam is investigated in this paper. The specific type of nonlinearity considered is of the hardening and softening Duffing-type, ...
