“…In this paper for facilitating comparisons, the detailed analyses about these micromechanical models are also made in Appendix A. Recently, with the improvement of computation capability of computer, many complicated numerical solutions, including perturbation-based stochastic homogenization analysis method [30], effective thermoelastic approach [31], Mori-Tanaka (M-T) method [32] and the finite element method (FEM) [33][34][35][36][37][38], are more and more used to predict the thermal expansion behaviors of composites.…”

The thermal expansion behaviors of neat epoxy resin and carbon fiber/epoxy unidirectional (UD) composites were experimentally and numerically studied in this paper. The dynamic mechanical analysis (DMA), thermogravimetric analysis (TG), differential scanning calorimetry (DSC) and thermal conductivity measurement were used to measure the thermo-mechanical properties of epoxy resin at different temperatures. The dilatometer was used to measure the thermal strains and linear CTEs of neat epoxy resin and UD composites. In addition, a mesoscale finite element model based on the periodic temperature and displacement boundary conditions was presented to analyze the thermal expansion behaviors of UD composites. The resin-voids representative volume element (RVE) was used to calculate the thermo-mechanical properties of several kinds of resin-voids mixed matrix. From the results it can be found that the glass transition temperature of epoxy resin, porosity and fiber orientation angle have significant effects on the thermal expansion behaviors of UD composites. The mesoscale finite element analyses (FEA) have obvious advantages than various existing analysis models by comparing their predictive results. The distributions of thermal displacement, thermal stress and thermal strain were extracted between the carbon fiber, resin-voids mixed matrix and their interface, and also between the front and back surfaces of the loading direction, to further investigate thermal expansion structure effects of UD composites. This paper revealed that the mesoscale FEA based on periodic temperature and displacement boundary conditions can be also used for thermal expansion researches of other complex structure composites.

“…In the last decades, many approaches were made on assessing the potential of micromechanica l models and estimating the accuracy by comparison with results of numerical simulations and experimental measurements [9][10][11]. Recently, Gusev presented time-domain finite element simulation for composites with different microstructures, including composites with viscoelastic coated spherical inclusions.…”

“…Many authors have focused their work on the influence of the geometrical structure of the multilayered composite [14][15][16]. Also, it have been considered different specific structures, as cylindrical [17,18], spherical [19,20] or truncated conical shell [21]. On the other hand, important studies have been developed in order to see the influence of the contact behavior in the interface of the components on the global properties of the composite [22][23][24].…”

The manuscript offers a methodology to solve the local problem derived from the homogenization technique, considering composite materials with generalized periodicity and imperfect spring contact at the interface. The general expressions of the local problem for an anisotropic composite with perfect and imperfect contact at the interface are derived. The analytical solutions of the local problems are obtained by solving a system of partial differential equations. In order to validate the model, the effective properties of the structure presented in the literature are obtained as particular cases. The solution of the local problem is used to extend the study to more complex structures, such as, wavy laminates shell composites with imperfect spring type contact at the interface. Also, the results are compared with the results for perfect and imperfect contact models available in the literature.
