Effective Properties Evaluation for Smart Composite Materials
(ABCM BRAZILIAN SOC MECHANICAL SCIENCES & ENGINEERINGRIO DE JANEIRO RJ, 2012)
The purpose of this article is to present a method which consists in the development of unit cell numerical models for smart composite materials with piezoelectric fibers made of PZT embedded in a non-piezoelectric matrix ...
Model for piezoelectric/ferroelectric composites polarized with interdigitated electrodes
(Elsevier, 2015-11)
A piezoelectric composite homogenization model (PCHM) is presented in this article. A systematic method for predicting the composite macroscopic history-dependent electromechanical response is developed and particularized ...
PTCa/PEEK composite acoustic emission sensors
(2006-10-01)
Composites made of Calcium-modified lead titanate (PTCa) and poly (ether-etherketone) (PEEK) high performance polymer matrix were prepared in the film form using a hot press. The ceramic volume fraction reaches up to 60 ...

Design of laminated piezocomposite shell transducers with arbitrary fiber orientation using topology optimization approach
(WILEY-BLACKWELLHOBOKEN, 2012)
Sensor and actuator based on laminated piezocomposite shells have shown increasing demand in the field of smart structures. The distribution of piezoelectric material within material layers affects the performance of these ...
Analytical formulae for electromechanical effective properties of 3-1 longitudinally porous piezoelectric materials
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
A unidirectional fiber composite is considered here, the fibers of which are empty cylindrical holes periodically distributed in a transversely isotropic piezoelectric matrix, The empty-fiber cross-section is circular and ...
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 ...
