TL;DR: In this paper, the shape memory effect due to martensitic transformation and reorientation of polycrystalline shape memory alloy (SMA) materials is modeled using a free energy function and a dissipation potential.

TL;DR: A micromechanics method based on the Mori-Tanaka averaging scheme is used to predict the effective thermomechanical properties of composite materials reinforced by Shape Memory Alloy (SMA) fibers.

TL;DR: The phenomenological SMA equations developed in Part I are used in this article to derive the free energy and dissipation of a SMA composite material, which consists of solving a boundary value problem formulated over a mesoscale representative volume element, followed by an averaging procedure to obtain the macroscopic composite constitutive equations.

TL;DR: In this article, a finite element analysis and micromechanics based averaging of a representative volume element (RVE) is performed to determine the effective dielectric, magnetic, mechanical, and coupled-field properties of an elastic matrix reinforced with piezoelectric and piezomagnetic fibers as functions of the phase volume fractions, the fiber arrangements in the RVE, and the fiber material properties with special emphasis on the poling directions of the pieziolectric or piezusmagnetic fibers.

TL;DR: It is shown that graphene paper supercapacitor electrodes containing aramid nanofibers as guest materials exhibit extraordinarily high tensile strength and excellent electrochemical stability, nearly rivaling those of graphene-based pseudocapacitors.
