Abstract
The aim of this paper focused on obtaining the optimum cruciform geometry of reinforced magnetorheological elastomers (MRE) to perform homogeneous equibiaxial deformation tests, by using optimization algorithms and Finite Element Method (FEM) simulations. To validate the proposed specimen geometry, a digital image correlation (DIC) system was used to compare experimental result measurements with respect to those of FEM simulations. Moreover, and based on the optimum cruciform geometry, specimens produced from MRE reinforced with carbonyl-iron microparticles or iron nanoparticles were subjected to equibiaxial loading and unloading cycles to examine their Mullin’s effect and their residual strain deformations.
Highlights
The addition of materials of different nature, size, and morphology to neat polymers leads to new reinforced polymeric composites with physical and mechanical properties that need to be determined, since during their manufacturing processes or service conditions [1,2,3] these could be subjected to three-dimensional deformation states that require a good understanding of their mechanical properties to predict their qualitative and quantitative behavior [4,5]
The common practice of using tensile testing to predict the material’s response is insufficient to account for anisotropic effects that could arise in reinforced polymeric materials
The experimental data obtained from these tensile tests do not provide sufficient information to appropriately identify constitutive equations to describe the material behavior under a variety of complex loading conditions
Summary
The addition of materials of different nature, size, and morphology to neat polymers leads to new reinforced polymeric composites with physical and mechanical properties that need to be determined, since during their manufacturing processes or service conditions [1,2,3] these could be subjected to three-dimensional deformation states that require a good understanding of their mechanical properties to predict their qualitative and quantitative behavior [4,5]. To validate the proposed specimen geometry, a digital image correlation (DIC) system, Aramis V8, was used Based on this cruciform geometry, specimens made from polydimethylsiloxane (PDMS, silicone rubber) elastomer reinforced with iron micro- or nanoparticles were subjected to equibiaxial loading and unloading cycles to examine the Mullins effect and residual strain deformations.
