Effect of a viscoelastic interface on the transverse behavior of fiber-reinforced composites
TLDR
In this paper, a simple linearly viscoelastic model is used to characterize the stiffness and viscosity of the interface separating the libers and the matrix, and an approximate representation of the time-dependent macroscopic behavior of the composite is derived analytically and compared with the numerical results.About:

Viscoelastic interphases in polymer–matrix composites: theoretical models and finite-element analysis
Frank T. Fisher,L. C. Brinson +1 more
TL;DR: In this paper, the authors investigated the mechanical properties of a three-phase viscoelastic composite by using two micromechanical models: the original Mori-Tanaka (MT) method and an extension of the MT solution to treat fibers with interphase regions.

On the Elastic Field of a Shpherical Inhomogeneity with an Imperfectly Bonded Interface
Z. Zhong,Shaker A. Meguid +1 more
TL;DR: In this article, a unified and explicit elastic solution to the problem of a spherical inhomogeneity with an imperfectly bonded interface is proposed. But the authors assume that the tangential and the normal displacement jumps are proportional to the associated tractions, and the elastic disturbance due to the presence of imperfectly-bonded spherical inclusion is decomposed into two parts: the first part is formulated in terms of an equivalent nonuniform eigenstrain distributed over a perfectly bonded spherical inclusion, while the second part is formed by an imaginary Somigliana dislocation field.

A local finite element implementation for imposing periodic boundary conditions on composite micromechanical models
TL;DR: In this paper, a method that uses a local implementation of the constraints that does not adversely affect the computational speed has been proposed to model composite materials using larger representative volume elements (RVEs) with greater numbers of inclusions.

Micromechanical modeling of viscoelastic composites with compliant fiber–matrix bonding
Anton Matzenmiller,S. Gerlach +1 more
TL;DR: In this article, the authors used the micromechanical method of cells to calculate the average time-dependent constitutive properties of the homogenized substitute continuum from the viscoelastic material properties and volume fractions of the individual phases as well as from the interphase behavior of polymeric fiber composites.

Finite-Element Formulation of a Nonlocal Hereditary Fractional-Order Timoshenko Beam
TL;DR: In this article, the response of the nonlocal Timoshenko beam model when viscoelastic long-range interactions are included, modeled by Caputo's fractional derivatives, is investigated.

A treatise on the mathematical theory of elasticity
TL;DR: Webb's work on elasticity as mentioned in this paper is the outcome of a suggestion made to me some years ago by Mr R. R. Webb that I should assist him in the preparation of a work on Elasticity.

Solutions for effective shear properties in three phase sphere and cylinder models
Richard M. Christensen,K.H. Lo +1 more
TL;DR: In this paper, the effective shear modulus of two types of composite material models are compared. And the results are found to differ from those of the well-known Kerner and Hermans formulae for the same models.

A Continuum Model for Void Nucleation by Inclusion Debonding
TL;DR: In this paper, a boundary value problem simulating a periodic array of rigid spherical inclusions in an isotropically hardening elastic-viscoplastic matrix is analyzed and the effect of the triaxiality of the imposed stress state on nucleation is studied and the numerical results are related to the description of void nucleation within a phenomenological constitutive framework.
