Numerical unit cell models of 1-3 periodic composites made piezoceramic unidirectional cylindrical fibers embedded in a soft non-piezoelectric matrix are developed. The is used for prediction the effective coefficients transversely isotropic piezoelectric fiber composite. Special emphasis placed on formulation boundary conditions that allows simulation all modes overall deformation arising from any arbitrary combination mechanical and electrical loading. numerical approach based finite...
In this work, based on the periodic unfolding homogenization technique, limiting equations modelling behaviour of three-dimensional magneto-electro-elastic structures are rigorously established. The local problems and corresponding homogenized coefficients elastic, dielectric, magnetic permittivity, piezoelectric, piezomagnetic magneto-electric (ME) tensors explicitly described. model is exemplified for laminated composites a unified general formula all effective properties multilaminated...
In previous papers Herrera developed a theory of connectivity that is applicable to the problem connecting solutions defined in different regions, which occurs when solving partial differential equations and many problems mechanics. this paper we explain how complete conditions can be used replace boundary integral situations. We show completeness satisfied not only steady-state such as potential, reduced wave equation static quasi-static elasticity, but also time-dependent heat dynamical...
The asymptotic homogenization method is applied to characterize the effective behaviour of periodic multi-laminated micropolar elastic heterogeneous composites under perfect contact conditions. local problem formulations and analytical expressions for stiffness torque coefficients are derived centrosymmetric case. One main findings in this work analysis rotations effect layers' constitutive properties on mechanical response bi-laminated composites. effects microstructure interfacial...
The method of matched asymptotic expansions is used to look into the problem scattering plane SH waves by topographic irregularities a restricted range in an otherwise half-space when characteristic length dimension irregularity much smaller than wavelength incident wave. In contrast previous work slope remains arbitrary. Expressions for near and far scattered fields are obtained. Comparison between this theory regular perturbation technique (which also assumes that has small slope) show...
A quasistatic unilateral frictionless contact problem for a rigid axisymmetric indenter pressed into homogeneous, linearly elastic and transversely isotropic layer bonded to half-space is considered. Using the general solution governing integral equation of an half-space, we derive exact equations force radius, which are then approximated under assumption that radius sufficiently small compared thickness layer. An asymptotic analysis resulting non-linear algebraic corresponding fourth-order...
