Shape memory effect and thermomechanical properties of shape memory polymer fabric composite in tension mode

Manzoor Ahmad, J. Luo, Dheraj Singh, Mohsen Miraftab

Fibers and fabrics are often used to reinforce shape memory polymers (SMPs) to improve their mechanical strength and properties, and the composites have been widely used in…

An investigation of structural composite laminates

M. Chowdhury

The following presentation is divided into two parts, A and B. The ultimate objective of this investigation is to compute the ‘extreme’ loading conditions that will cause failure…

Mechanical characteristics of doped soda-lime silica glass

M. Suszynska, M. Szmida, A. Cizman

The aim of the work described was to investigate the effect of the glass microstructure, changed during chemical and thermal treatments, upon the micro-hardness and microcracking…

Application of cohesive-zone models to delamination behaviour of composite material

L. Peng, X. Gong, K. Wong, L. Guillaumat

The parameters of cohesive elements have to be chosen correctly in the simulation of composite delamination by finite element method: such as interface strength, interface…

Laser cladding of Cu0.5NiAlCoCrFeSi high entropy alloy on AZ91D magnesium substrates for improving wear and corrosion resistance

T. Yue, K. Huang

To improve the wear and corrosion properties of AZ91D magnesium alloy, a Cu_0.5NiAlCoCrFeSi high entropy alloy (HEA) was fabricated on AZ91D magnesium substrate specimens by laser…

Magnetism and half-metallicity of some Cr-based alloys and their potential for application in spintronic devices

Yong Liu, S. Bose, J. Kudrnovský

We present results of the exchange interactions and Curie temperatures in some Cr-based chalcogenides and pnictides. The calculations are performed mostly for Zinc Blende (ZB…

The natural structure of woven 2D fabrics to reinforce textile composites

V. Choogin, E. Chepelyuk, P. Bandara, D. Hui

Development of the theory of natural structure of woven fabric for warp and weft threads in woven fabric upon release from external loadings in the woven machine on the basis of…

A research of the working surfaces of abrasive composites

A. Syromyatnikova, M. Safonova, A. Fedotov

In this paper, the method for the calculation of disperse fillers concentration on effective surface composite (active grains) is developed. The method is proven by research of…

The dynamic measurement uncertainty evaluation on coal mine pump performance testing systems

G. Wang, X. Xie, S. Jiao, L. Zhang, Q. Niu

In view of applying the static measurement theory to evaluate the measurement uncertainty of a testing system, this paper develops a comprehensive coal mine pump performance…

Physical properties and storage stability of asphalt binder modified with nanoclay and warm asphalt additives

M. Abdullah, K. Zamhari, N. Nayan, M. Hainin, M. Hermadi

Nowadays, researchers are interested in using the material at nanoscales as one of asphalt binder modifier. In this paper, Malaysian asphalt binder was modified with nanoclay and…

Versatile low-pressure plasma-enhanced process for synthesis of iron and iron-based magnetic nanopowders

P. Zelina, O. Jašek, V. Kudrle, B. David, N. Pizúrová, D. Pavliňák, Z. Voráč, D. Hemzal

Using microwave low-pressure discharge, we synthesised magnetic iron-oxide nanopowder from the iron pentacarbonyl precursor. We were able to vary the size and chemical composition…

Numerical modelling of castellated beams with hexagonal openings

Mostefa Mimoune, Mohammed Soltani, Abdelhamid Bouchair

In this paper, a numerical model is developed to predict the behaviour of castellated beams with hexagonal. The numerical model takes into account both material and geometric…
