Abstract

This paper deals with providing the effective elastic response of three-phase composites consist of a matrix filled with a random suspension of liquid-filled capsules firmly bonded to the matrix in the realm of small deformation theory. The capsules shell (interphases) and the matrix are considered to be elastic solids and the liquid is considered ideal. For this purpose, the solution for dilute concentrations of the interphases and the liquid particles are derived analytically. Then, the dilute solution is passed to an iterative technique to generate the non-dilute version of the solution. The non-dilute response is available in terms of a system of two nonlinear-coupled-ODE-initial-value problems. The results are confronted with the results of a 3D full-field FE analysis and experimental data and a good agreement is observed. The solution, provided here for polydisperse microstructures, allows for considering different thicknesses for the interphases and in turn can possibly account for different physical phenomena like the size and the surface tension effects. A comprehensive study on the effects of interphases (capsules shell) thickness and mechanical properties as well as the volume concentration of the capsules and the liquid particles on the overall elastic properties of three-phase liquid-filled composites are carried out. We show that although the addition of liquid particles to the matrix has deteriorating effects on the overall elastic properties of the composites, proper selection of the interphases can compensate for these negative effects.

液体颗粒和相间层对充液复合材料宏观弹性响应的相互作用

本文探讨了三相复合材料的有效弹性响应，三相复合材料由基体和牢固粘结在基体上的充满液体的胶囊的随机悬浮液组成。胶囊外壳（相间）和基体被视为弹性固体，液体被视为理想液体。为此，我们通过分析得出了间相和液体颗粒的稀释溶液。然后，通过迭代技术生成非稀释版的稀释解。非稀释响应可通过两个非线性耦合-ODE-初值问题系统获得。研究结果与三维全场 FE 分析结果和实验数据相比较，发现两者具有良好的一致性。本文提供的多分散微结构解决方案允许考虑不同厚度的相间层，进而可能解释不同的物理现象，如尺寸和表面张力效应。我们全面研究了相间层（胶囊外壳）厚度和机械性能以及胶囊和液体颗粒的体积浓度对三相充液复合材料整体弹性性能的影响。我们的研究表明，虽然在基体中添加液体颗粒会对复合材料的整体弹性性能产生不利影响，但适当选择相间层可以弥补这些负面影响。

期刊介绍： The aim of this journal is to provide ideas and information involving the use of the finite element method and its variants, both in scientific inquiry and in professional practice. The scope is intentionally broad, encompassing use of the finite element method in engineering as well as the pure and applied sciences. The emphasis of the journal will be the development and use of numerical procedures to solve practical problems, although contributions relating to the mathematical and theoretical foundations and computer implementation of numerical methods are likewise welcomed. Review articles presenting unbiased and comprehensive reviews of state-of-the-art topics will also be accommodated.
