This paper introduces a new method of determining the mechanical properties of carbon nanotube-polymer composites using a multi-inclusion micromechanical model with functionally graded phases. The nanocomposite was divided into four regions of distinct mechanical properties; the carbon nanotube, the interface, the interphase and bulk polymer. The carbon nanotube and the interface were later combined into one effective fiber using a finite element model. The interphase was modelled in a functionally graded manner to reflect the true nature of the portion of the polymer surrounding the carbon nanotube. The three phases of effective fiber, interphase and bulk polymer were then used in the micromechanical model to arrive at the mechanical properties of the nanocomposite. An orientation averaging integration was then applied on the results to better reflect macroscopic response of nanocomposites with randomly oriented nanotubes. The results were compared to other numerical and experimental findings in the literature.

Micromechanical modelling of carbon nanotube reinforced composite materials with a functionally graded interphase Taç, Vahidullah; Gürses, Ercan (SAGE Publications, 2019-12-01) This paper introduces a new method of determining the mechanical properties of carbon nanotube-polymer composites using a multi-inclusion micromechanical model with functionally graded phases. The nanocomposite was divided into four regions of distinct mechanical properties; the carbon nanotube, the interface, the interphase and bulk polymer. The carbon nanotube and the interface were later combined into one effective fiber using a finite element model. The interphase was modelled in a functionally graded m...
Micromechanical modeling of carbon nanotube – polymer composites Taç, Vahidullah; Gürses, Ercan; Department of Aerospace Engineering (2018) A micromechanics-based model is developed to simulate carbon nanotube – polymer nanocomposites and analyze its mechanical behavior. The nanocomposite is first divided into four distinct regions, or phases, based on mechanical behavior and density; the carbon nanotube, the interface, the interphase and the polymer. The finite element method was later used to combine the nanotube and interface phases into an effective fiber for better representation and incorporation of their roles and constitutive properties...
Computational modelling of carbon nanotube reinforced polymer composites Zuberi, Muhammad Jibran Shahzad; Esat, Volkan; Electrical and Electronics Engineering (2014-7) This thesis investigates the effects of chirality and size of single-walled carbon nanotubes (SWNTs) on the mechanical properties of both SWNTs and carbon nanotube reinforced epoxy composites (CNTRPs). First, a novel 3D beam element finite element model is developed based on equivalent-continuum mechanics approach and used for replacing C-C chemical bond for modelling SWNTs. The effects of diameter and chirality on the Young’s moduli, shear moduli, shear strains and Poisson’s ratios of SWNTs are studied. Fo...
A constitutive model for finite deformation of amorphous polymers FLEISCHHAUER, R.; Dal, Hüsnü; KALISKE, M.; SCHNEIDER, K. (2012-12-01) The paper introduces a three-dimensional constitutive model for the mechanical behavior of amorphous polymers, thermosets and thermoplastics. The approach is formulated in terms of finite deformations, appropriate for glassy polymers. The rheology of the model consists of a Langevin-type free energy function for the energy storage due to molecular alignment connected in parallel to a Maxwell element with a viscoplastic dashpot. The model proves successful for the constitutive description of glassy polymers ...
Micromechanical Modelling of Size Effects in Microforming Yalçınkaya, Tuncay; SIMONOVSKI, IGOR; ÖZDEMİR, İZZET (2017-09-01) This paper deals with the micromechanical modelling of the size dependent mechanical response of polycrystalline metallic materials at micron scale through a strain gradient crystal plasticity framework. The model is implemented into a Finite Element software as a coupled implicit user element subroutine where the plastic slip and displacement fields are taken as global variables. Uniaxial tensile tests are conducted for microstructures having different number of grains with random orientations in plane str...
