Experimental damage detection using system norms
(2006-12-01)
Nowadays there is great interest in structural damage detection in systems using nondestructive tests. Once the failure is detected, as for instance a crack, it is possible to take providences. There are several different ...

Machine learning identification of piezoelectric properties.
(MDPI, 2021)
The behavior of a piezoelectric element can be reproduced with high accuracy using numerical simulations. However, simulations are limited by knowledge of the parameters in the piezoelectric model. The identification of ...
Proposal of a nonlinear piezoelectric coupling term to energy harvesting interactions
(2015-01-01)
Nowadays, new technologies have triggered the needs of new energy sources, smaller and more efficient, so the research about energy harvesting has increased substantially. Several researchers have developed the conversion ...
Modeling and analysis of laminate composite plates with embedded active-passive piezoelectric networks
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
The objective of this work is to present the finite element modeling of laminate composite plates with embedded piezoelectric patches or layers that are then connected to active-passive resonant shunt circuits, composed ...
Collagen-hydroxyapatite films: piezoelectric properties
(Elsevier B.V., 2001-10-03)
In this paper we report a study of the physicochemical, dielectric and piezoelectric properties of anionic collagen and collagen-hydroxyapatite (HA) composites, considering the development of new biomaterials which have ...

Finite element homogenization technique for the characterization of d(15) shear piezoelectric macro-fibre composites
(IOP PUBLISHING LTD, 2011)
A finite element homogenization method for a shear actuated d(15) macro-fibre composite (MFC) made of seven layers (Kapton, acrylic, electrode, piezoceramic fibre and epoxy composite, electrode, acrylic, Kapton) is proposed ...
Identification of Elastic, Dielectric, and Piezoelectric Constants in Piezoceramic Disks
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
Three-dimensional modeling of piezoelectric devices requires a precise knowledge of piezoelectric material parameters. The commonly used piezoelectric materials belong to the 6mm symmetry class, which have ten independent ...
