Seismic damage to buried underground pipelines was observed in the Canterbury 2010-2011 earthquakes, New Zealand. The post earthquake reconnaissances of these failures provide useful information about the failure modes and ...

Extrusion dies are usually manufactured with a rectangular pocket in front of the actual die opening. Finite element simulations demonstrate that curved or slant shaped pockets can assist in a more homogenous material flow ...

In the event of any contamination found in the river, the estimation of subsequent concentration of contamination in the river with time is very important for post-accident management plans. It is totally depended on total ...

This paper describes the preliminary development of a 3-D finite element model of a chip seal road surfacing. A 3-D chip matrix was constructed using X-ray tomography scans of multiple layer seal samples removed from a ...

A method for the analysis of particle orientations in unbound granular basecourse is described. The positions and orientations of the aggregate particles in compacted specimens of aggregate were fixed by filling the air ...

The mechanical properties of processed metal depend greatly on the micro-structural changes during the extrusion process. A clear theoretical concept of the thermodynamics and tribology of the metal extrusion process with ...

This paper presents the development of an inverse model that may be used to estimate the source term parameters for a polluting gas released into the atmosphere from a point above the ground. The model uses measured pollution ...

This paper presents an inverse modelling procedure to estimate the location and release rate of atmospheric pollution. The input to this model requires measured pollution concentration at a minimum of three observation ...

This paper describes a mathematical modelling technique which may be used to identify the origin and release history of a polluting gas released into the atmosphere from a point source. The inputs to this model are: pollution ...
