A 3D Monte Carlo simulation and percolation network model for hybrid nanocomposites reinforced by carbon nanotubes (CNTs) and carbon black (CB) nanoparticles (NPs) is established to investigate the percolation probability and piezoresistivity considering electron tunneling effect. Firstly, a Monte Carlo algorithm is developed to form a representative volume element filled with randomly oriented CNTs and randomly dispersed CB NPs. Later, a percolation like network model is developed to determine ...

The primary goal of this work is to design a novel magnetorheological damper with selectable performance parameters to improve the environmental adaptability of vibration systems equipped with such a damper and to provide a new idea for the design of magnetorheological dampers. The feasibility of the new idea is verified in both principle and experiment. The conceptual design, working principle analysis, magnetic design and prototype development of the magnetorheological damper are carried out. ...

Recent research shows that flexoelectricity may prominently affect the electromechanical coupling responses of elastic dielectrics at the nanoscale. From the perspective of devices design, it is urgent to know how the input parameters affect the electromechanical coupling behaviors of flexoelectric nanostructures. In this work, global sensitivity analysis is applied to elastic dielectric nanoplates to decompose the attribution of each of the parameters. Meanwhile, the existing hierarchical regre...

The narrow band gap width caused by local resonance is the shackle for the further development of conventional metamaterials. In this paper, a novel type of hierarchical metamaterial containing parallel multiple resonators is presented, whose ultra-broadband vibration suppression property originates from a rational gradient design. Characterization of dispersion relations and bandgap characteristics of the one-dimensional outward-hierarchical lattice system reveals the variation of bandgap bound...

Conform and non-conformal contact problem in the face of piezoelectric motors can be hard to grasp, especially both the friction drive and wear lifespan are considered. Flowing the classical contact issue, an elastic brittle flat punch as the driving tip of the stator for piezoelectric devices is chosen and the contact behaviour under elliptical ultrasonic vibration is investigated using finite element method. A limited stress analysis is conducted after the quasi-static contact of the driving t...

In this paper, a size dependent numerical model for free vibration and bending analyses of hexagonal beryllium crystal (HBC) nanoplates is presented. Based on the nonlocal strain gradient theory (NSGT), both nonlocal and strain gradient effects are considered in the present model. In addition, the behavior of HBC material can be considered as an anisotropic one. By employing principle of virtual displacement (PVD), the governing equations of motion for a Galerkin weak for the higher-order shear ...

In this work, the thermoelastic dissipation (TED) for circular-cross-sectional micro/nanoring model is studied including the single-phase-lag (SPL) time based on the non-Fourier heat conduction model. The toroidal solid ring is simple to manufacture and thus the potential is high for future development. Also, the present model is more precise than the 1D or 2D beam or rectangular-cross-sectional ring because the governing equation is established by 3D coordinate system. Moreover, the SPL shows t...

This article aims to utilize IsoGeometric analysis (IGA) and Level set method for topology optimization of elastoplastic plane stress problems. The IGA is employed to model geometry of the problem and calculate unknown displacements by satisfying equilibrium for materially-nonlinear problems. The von Mises elastoplastic material behavior model with and without isotropic strain hardening is utilized. The normal velocity is derived by the pointwise gradient based sensitivity analysis of the Level ...

The use of metal-polymer membrane laminates for gossamer space structures emerge in recent times. Wrinkle formation, fold-line effect, and wrinkle minimization are more dominant in inflatable space structures and solar sail applications. In this article, the authors explored a novel work, wrinkle-crease interaction, for Aluminium-Kapton thin-film laminates. Introduction of non-avoidable crease profile adds uniqueness for laminates under in-plane shear deformation. A representative micro-material...

The coupling effect between the vibration of the electric components and the wave propagation is the critical factor that should be considered in the optimization on the layout of the electric components in the spacecrafts. Different from the case considered in our previous job, the layout of the electronic components on the spacecraft is always asymmetric, thus, investigating the wave propagation characteristics in an asymmetric plate is more meaningful than that in a symmetric one. As a compan...
