A technique for the multiobjective optimisation of laminated composite structures using genetic algorithms and finite element analysis
A methodology for using genetic algorithms with the finite element method to minimise a weighted sum of the mass and deflection of fibre reinforced structures with several design variables is described. The design constraint ...
Towards greener infrastructure
Design optimization of anisotropic pressure vessels with manufacturing uncertainties accounted for
Accurate optimal design solutions for most engineering structures present considerable difficulties due to the complexity and multi-modality of the functional design space. The situation is made even more complex when ...
Buckling and sensitivity analysis of nonlocal orthotropic nanoplates with uncertain material properties
Accurate estimates of the orthotropic properties of nano-materials are usually not available due to the difficulties in making measurements at nano-scale. However the values of the elastic constants may be known with some ...
Melt blend studies of nanoclay-filled polypropylene (PP)–high- density polyethylene (HDPE) composites
The objective of this work is to study how the rheological factors of unfilled and nanoclay-filled HDPE– PP blend series influence the structure, morphology, and mixing characteristics. For this study, a series of HDPE–PP ...
Reuse of cured epoxy as a reinforcement in an epoxy composite
This article discusses the reuse of a thermoset-based epoxy polymer. In this method, cured epoxy polymer is ground to powder of particle size ranging from 1 to 30 μm. The ground epoxy is then filled in an epoxy polymer to ...
Comparison between conditions of major roads within and outside the port of Durban
Over the past years road traffic has increased at the Port of Durban. Due to the lack of maintenance, this has resulted in road deterioration. Roads are considered as the most important transport mode at the Port of Durban. ...
Rea Vaya : South Africa’s first bus rapid transit system
Today, both the public and private transport sectors are facing challenges as a result of an increase in vehicle ownership and the suburbanisation of both firms and residences in the world. In the past, public transport ...
Splitting vacancy voids in the grain boundary region by a post-cascade shock wave
(Institute of Problems of Mechanical Engineering, 2013)
The structural transformation of vacancy voids in the grain boundary region of the bicrystal under the influence of post-cascade shock waves is studied with the aid of molecular dynamics simulations. It is shown that the ...
The innovation landscape of South Africa under new intellectual property management policy
(Innovation Summit, 2013)
The new intellectual property (IP) policy currently under development by the Department of Trade and Industry will likely define the future innovation landscape in South Africa. This is in line with the direction the country ...
