Carlos González,Javier LLorca +1 more
TLDR
In this paper, the mechanical behavior of polymer-matrix composites unidirectionally reinforced with carbon or glass fibers subjected to compression perpendicular to the fibers was studied using computational micromechanics using finite element analysis of a representative volume element of the microstructure idealized as a random dispersion of parallel fibers embedded in the polymeric matrix.About:

Multiscale modeling of composite materials: a roadmap towards virtual testing
Javier LLorca,Carlos González,Jon M. Molina-Aldareguia,Javier Segurado,Rocío Seltzer,Federico Sket,M. Rodríguez,S. Sadaba,R. Muñoz,Luis P. Canal +9 more
TL;DR: A bottom-up, multiscale modeling approach is presented to carry out high-fidelity virtual mechanical tests of composite materials and structures and the roadmap for the extension of the current strategy to include functional properties and processing into the simulation scheme is delineated.

Micromechanical modelling of the transverse damage behaviour in fibre reinforced composites
Ted J. Vaughan,Conor T. McCarthy +1 more
TL;DR: In this paper, the effect of debonding and thermal residual stress on the transverse damage behavior of a unidirectional carbon fiber reinforced epoxy composite was examined, and it was found that for a weak fibre-matrix interface, the presence of thermal residual stresses can induce damage prior to mechanical loading.

Micromechanical analysis of polymer composites reinforced by unidirectional fibres: Part I – Constitutive modelling
TL;DR: In this paper, a pressure dependent, elasto-plastic thermodynamically consistent damage model was used to model the interface between a typical epoxy matrix and fibres.

Micromechanical analysis of polymer composites reinforced by unidirectional fibres: Part II – Micromechanical analyses
TL;DR: In this article, a constitutive damage model for an epoxy matrix on micromechanical analyses of polymer composite materials is presented. But the authors focus on the influence of the interface between fiber and matrix, as well as to the influence on the strength properties of the composite, damage initiation and propagation under different loading conditions.

Effective properties of composite materials with periodic microstructure : a computational approach
TL;DR: In this paper, two different families of numerical methods are considered to solve the problem of a homogeneous linear reference material undergoing a nonhomogeneous periodic eigenstrain, and the relative merits of the two methods are compared and several examples are discussed.
