A new modeling approach is proposed for predicting the bulk electromechanical properties of piezoelectric composites. The proposed model offers the same level of convenience as the wellknown Mori-Tanaka method. The electromechanical properties of four piezoelectric polymer composite materials are predicted with the proposed, Mori-Tanaka, Self-consistent methods, and detailed finite element anal...

the theoretical and experimental investigation on the thermo-mechanical properties of carbon nanotube (cnt) as reinforcer for oil and gas pipes has increasingly become a hot research area for many engineers and material scientists in recent years. this is mainly due to the advent of the new composite material systems that exhibit exotic material and mechanical properties as compared to the trad...

The purpose of the present work is to analyze the modulus of elasticity of graphene (Gr) sheet-reinforced metal matrix nanocomposites (MMNCs) using a homogenized model based on the Mori-Tanaka micromechanics approach. The main focus is to investigate the effects of Gr sheet agglomeration on the MMNC macroscopic elastic modulus. Also, the role of aligning Gr sheets in the mechanical performance ...

Micromechanics models for the stiffness of aligned short-fiber composites are reviewed and evaluated. These include the dilute model based on Eshelby’s equivalent inclusion, the self-consistent model for finite-length fibers, Mori-Tanaka type models, bounding models, the Halpin-Tsai equation and its extensions, and shear lag models. Several models are found to be equivalent to the Mori-Tanaka a...

In the present work, we propose to confront two modeling techniques for predicting macroscopic properties of short alfa fiber-reinforced polypropylene composites. The first was a micromechanical analysis using Mori-Tanaka, Self-consistent, Diluted, Voigt, Reuss, and Neerfeld-Hill models. second digital, specific finite element technique called Projected Fiber (PF) approach. framework this study...

This paper presents for the first time an extended Mori-Tanaka approach aimed at identifying little-explored piezoelectric response of unidirectional nanoporous composites with energetic surfaces. The interface is simulated using generalized Gurtin-Murdoch coherent model considering nonvanishing in-plane surface stress and electric displacement. analytical solutions Eshelby’s inhomogeneity prob...
