Resilience And Sustainability In The Management Of Landslides, Phillip N. Flentje, Robin N. Chowdhury Jan 2018

Resilience And Sustainability In The Management Of Landslides, Phillip N. Flentje, Robin N. Chowdhury

Faculty of Engineering and Information Sciences - Papers: Part A

There are many regions worldwide which are susceptible to landslides, which cause loss of life and adverse impacts to infrastructure, environment and communities. Landslides are often triggered by exceptional rainfall and large-magnitude earthquakes. A range of strategies and methods have been developed to mitigate the occurrence of landslides and to reduce their impact, including risk to human safety. The adopted approaches and systems must be sustainable and resilient in relation to the communities that are at risk. This paper refers to an Australian regional case study of urban landslide management in the Wollongong region, New South Wales. The research carried ...

A350 grade black mild steel is one of the most widely used structural materials in the world, being commonly found in buildings, bridges and offshore structures.Welding is commonly used to join two plates of structural steel and this often takes the form of a T-butt.In addition, other more complex geometrical joints are often simplified for stress analysis purposes by approximating them as 2-D T-butt plate models (e.g. skewed T-joints, cruciform welded joints, tubular welded joints, pipe–plate joints, etc.).However, all such welds are potentially susceptible to fatigue crack initiation and slow but accelerating growth arising as ...

Particulate reinforced metal matrix composites (PRMMCs) are of interest owing to the low cost of their raw materials and their ease of fabrication, making them suitable for applications requiring relatively high-volume production. The improved properties of PRMMCs result from the addition of hard ceramic particles (such as Al2O3 or SiC); the size, shape, volume fraction, interfacial properties and distribution of these (together with the fabrication method) determine the mechanical behaviour of the composite. However, PRMMCs have inferior ductility, toughness and low-cycle fatigue properties compared with unreinforced alloys, often limiting their usefulness in practice. Reinforcements of between 15 volume % and 25 ...
