Shear nonlinear constitutive relationship of needled C/C-SiC composite

In order to investigate the shear damage behavior of needled C/C-SiC composite, in-plane shear load-unload experiments were conducted firstly, and the shear fracture morphologies of the composites were observed by SEM. Then, a plasticity-damage combined nonlinear constitutive model was established to describe the nonlinear mechanical behavior of the composite, and the power function was used to characterize the relationship between equivalent plastic strain and equivalent stress. Finally, an exponent-form damage variable was introduced to describe the shear stiffness degradation based on the Weibull distribution law of shear strength, and the parameters in model were determined by fitting of the experimental data. The results show that the composite has obvious residual deformation after unloading, the unloading modulus degenerates with the increase of load continually, which exhibits obvious shear nonlinearity characteristic. A large number of fiber bundles and fiber single yarns in non-woven cloth were pulled out, and the failures tend to occur at needling positions. For the irregular distribution of imperfection at needling positions, shear strength possesses dispersibility at some extent, and conforms to exponent-form Weibull statistical distribution law. The shear nonlinearity of the composite was induced by inner damages such as matrix cracking and fiber/matrix interfacial debonding etc., which can be described by plasticity deformation and stiffness properties degradation from a macro perspective. The conclusions obtained verify that the constitutive model can fully describe the in-plane shear nonlinear behavior of needled C/C-SiC composite. © 2016, BUAA Culture Media Group Ltd.

Design and fabrication of novel optimized electrode materials are important for the development of new batteries for energy storage applications. Herein, we report on a hierarchical bulk electrode material with a tailored nanostructure that which consists of three components: a NH 4 V 4 O 10 nanowire as an active skeleton, an intermediate polymer layer (polypyrrole, PPy), and a metal oxide layer (MnO 2 ) as the outside shell. The NH 4 V 4 O 10 -PPy-MnO 2 nanowires exhibit present higher capacitance than that of the simple NH 4 V 4 O 10 -PPy [email protected] or NH 4 V 4 O 10 nanowires. The structure of double shells of combined PPy and MnO 2 is a key factor in enhancing their electrochemical performance including high specific capacitance and excellent cycling stability. Our V-based [email protected] @shell structure can serve as freestanding, compressible electrodes for various energy devices.

We present a method to carry out electrical and opto-electronic measurements on 2D materials using carbon fiber microprobes to directly make electrical contacts to the 2D materials without damaging them. The working principle of this microprobing method is illustrated by measuring transport in MoS2 flakes in vertical (transport in the out-of-plane direction) and lateral (transport within the crystal plane) configurations, finding performances comparable to those reported for MoS2 devices fabricated by conventional lithographic process. We also show that this method can be used with other 2D materials. Copyright © 2017, The Authors. All rights reserved.

A model is proposed based on a Fourier series method to analyse the interactive bending wrinkling behaviour of inflated beams. The whole wrinkling evolution is tracked and divided into three stages by identifying the bifurcations of the equilibrium path. The critical wrinkling and failure moments of the inflated beam can then be predicted. The global-local interactive buckling pattern is elucidated by the proposed theoretical model and also verified by non-contact experimental tests. The effects of geometric parameters, internal pressure and boundary conditions on the buckling of inflated beams are investigated finally. The results reveal that the interactive buckling characteristics of an inflated beam under bending are more sensitive to the dimensions of the structure and boundary conditions. We find that for beams which are simply supported at both ends or clamped and simply supported, boundary conditions may prevent the wrinkling formation. The results provide significant support for our understanding of the bending wrinkling behaviour of inflated beams. © 2016 The Author(s) Published by the Royal Society. All rights reserved.

With honeycomb lattice of sp2 hybridized carbon atoms, graphene has demonstrated excellent electrical and mechanical properties. One of its promising applications is to fabricate graphene-ceramic composite to improve the mechanical properties. In order to quantify the strength between graphene-ZrB2 interactions, molecular dynamic method was utilized to simulate typical interface of graphene/ZrB2 ceramic structure. Berendsen method was used to control the temperature and pressure during the whole simulation process. Universal potential function was employed to simulate the force filed between graphene and ZrB2 structure. The binding structures of graphene/ZrB2 (0001) interface were analyzed in detail and the bonding energy of the interface was calculated. The influence of numbers of graphene layer and sandwich structures on the bonding energy of interface is discussed. The study helped to understand the influence of graphene on mechanical properties of ZrB2 ceramic. © (2015) Trans Tech Publications, Switzerland.

The fabrication of artificial materials by stacking of individual two-dimensional (2D) materials is amongst one of the most promising research avenues in the field of 2D materials. Moreover, this strategy to fabricate new man-made materials can be further extended by fabricating hybrid stacks between 2D materials and other functional materials with different dimensionality making the potential number of combinations almost infinite. Among all these possible combinations, mixing 2D materials with transition metal oxides can result especially useful because of the large amount of interesting physical phenomena displayed separately by these two material families. We present a hybrid device based on the stacking of a single layer MoS2 onto a lanthanum strontium manganite (La0.7Sr0.3MnO3) thin film, creating an atomically thin device. It shows a rectifying electrical transport with a ratio of 103, and a photovoltaic effect with Voc up to 0.4 V. The photodiode behaviour arises as a consequence of the different doping character of these two materials. This result paves the way towards combining the efforts of these two large materials science communities. Copyright © 2017, The Authors. All rights reserved.
