Wear

this paper focuses on the adhesion failure between the asphalt wearing course and the steel plate, and the temperature influence on the mechanical behavior of the orthotropic deck. Orthotropic steel bridge decks (OSBDs) have been widely used in long span bridges with many advantages, however, the long-term performance of the asphalt wearing course is still questionable.

In this thesis, the rolling contact wear of 52100 bearing steel and Over-aged Magnesia-Partially-Stabilised Zirconia (OA-Mg-PSZ) ceramic are examined using a newly developed rolling contact wear test rig. The new wear test rig simulates the system geometry of an un-lubricated hybrid (ceramic and steel) ball bearing. The new wear test rig is versatile in that it allows low cost samples to be utilised resulting in a larger number of samples that can be tested.

The majority of ready-to-wear shoes available in Australia are currently made in South-East Asian countries, mimicking current fashion styles, but compromising on quality to reduce cost for the Western market. It can be a challenge for women to purchase a suitable pair of dress shoes that is visually pleasing, functional and appropriate for a work environment. This research project investigated the availability of suitable dress footwear for working women within the Australian market.

This research project explores the negative environmental impacts of anthropogenic debris by investigating these found materials within the medium of contemporary jewellery objects. Contemporary jewellery objects are a powerful artistic medium. We can wear jewellery on our bodies and carry it with us. Jewellery can sit on or through the body, and at the same time extend beyond our bodies. Jewellery objects can resonate their own space, to be watched, observed publicly or privately, inviting the wearer or voyeur to think, to enquire, to remember and to investigate.

While it is recognised that knitted fabrics may have their place in firefighting PPC, especially for undergarments, from the point of view of fire performance, strength and presentation, woven fabric constructions appear to be more suitable for work wear applications. Hence, this study is concerned with developing and testing a range of functional, woven Station Wear fabrics designed to enhance flame protection, durability and thermo-physiological comfort properties. In trying to improve all three aspects, a compromise in the properties of fabrics developed would be very likely.
