Journal ArticleDOI
Closed-form expressions for the effective coefficients of a fiber-reinforced composite with transversely isotropic constituents – II. Piezoelectric and square symmetry
Julián Bravo-Castillero,Julián Bravo-Castillero,Raúl Guinovart-Díaz,Federico J. Sabina,Reinaldo Rodríguez-Ramos,Reinaldo Rodríguez-Ramos +5 more
TL;DR: Rodriguez-Ramos et al. as mentioned in this paper considered a composite material with unidirectional cylindrical fibers periodically distributed, where each periodic cell is a binary homogeneous piezoelectric medium with square symmetry in welded contact at the interface.
Journal ArticleDOI
Unit cell models of piezoelectric fiber composites for numerical and analytical calculation of effective properties
Harald Berger,Sreedhar Kari,Ulrich Gabbert,Reinaldo Rodríguez-Ramos,Julián Bravo-Castillero,Raúl Guinovart-Díaz,Federico J. Sabina,Gérard A. Maugin +7 more
TL;DR: In this article, a numerical unit cell model of 1-3 periodic composites made of piezoceramic unidirectional cylindrical fibers embedded in a soft non-piezoelectric matrix is developed.
Journal ArticleDOI
Closed-form expressions for the effective coefficients of fibre-reinforced composite with transversely isotropic constituents. I: Elastic and hexagonal symmetry
Raúl Guinovart-Díaz,Julián Bravo-Castillero,Julián Bravo-Castillero,Reinaldo Rodríguez-Ramos,Federico J. Sabina +4 more
TL;DR: In this paper, the effective elastic, piezoelectric and dielectric properties of reinforced PIE composite materials with unidirectional cylindrical fibres periodically distributed in two directions at an angle π/3 by means of the asymptotic homogenization method were determined.
Journal ArticleDOI
On local indentation and impact compliance of isotropic auxetic materials from the continuum mechanics viewpoint
TL;DR: In this article, the negative Poisson ratio with regard to the quasi-static and dynamic indentation compliances for isotropic homogeneous materials is considered and the effect of Poisson's ratio on these compliances is investigated.
Journal ArticleDOI
Evaluation of influence of interphase material parameters on effective material properties of three phase composites
Sreedhar Kari,Harald Berger,Ulrich Gabbert,Raúl Guinovart-Díaz,Julián Bravo-Castillero,Reinaldo Rodríguez-Ramos +5 more
TL;DR: In this article, the influence of inter-phase parameters like stiffness and volume fraction of interphase on effective material properties of transversely randomly distributed uni-directional fiber composites and randomly distributed spherical particle composites is studied.
