A/Prof Abrahams is in the department of Mechanical and Aerospace Engineering. His main research interests include:Laser cladding of rails and wheels, friction stir welding and processing, fracture and fatigue of aircraft structures, applying nano coatings and advanced techniques to improve wear fracture and fatigue properties of alloys and the structural integrity of aircraft structures. Improving fatigue properties of aluminium and magnesium alloys using friction-stir processing and thermo-mechanical techniques.

Whilst employed as a research associate at the UNSW, A/Prof Abrahams completed his PhD in Fracture Mechanics in 1990 from the same university. He spent the next two years at UNSW and Melbourne University as a Postdoctoral Research Fellow (1990-1992).

A/Prof Abrahams’ uninterrupted 27 year track record is evident from his academic distinctions, awards and recognition of research work through 220 top international journal publications in the areas of improving material properties (wear, fatigue and Fracture) of light alloys and steels using thermo-mechanical techniques, fracture mechanics, and structural integrity properties. At prestigious research institutions (Melbourne, UNSW and Monash) his research activities have always been directly relevant to industrial applications and in this time A/Prof Abrahams has been the Head of postgraduate Research for eight years in the Department of Mechanical and Aerospace Engineering, Monash University. Over the past five years he has published 43 journal papers (34 of 43 journal papers are in high impact factor journals). He has attracted several ARC Discovery, Linkage and LIEF grants (cash commitment ~ $4.5m).

A/Prof Abrahams currently spends 60% of his time on research and the supervision of PhD students and 40% on undergraduate teaching. Other large industry-sponsored projects include grants from ANSTO, Hard Chrome Engineering, AWI, CSIRO, and grants from major alumina. His professional distinctions include: membership of the review board of prestigious international conferences (e.g International Congress of Fracture (ICF11), International conference of the International institute of welding (IIW), and International Congress on Mechanical behaviour of materials. Furthermore he has been regularly invited to present keynote lectures at several international conferences.

A/Prof Abrahams has also established an advanced material testing laboratory with dedicated facilities (a nano scale tensile testing rig) for evaluating material characteristics, interfacial fracture toughness and delimitation of carbon nano tubes and servo-hydraulic testing machines for fatigue and fracture toughness testing of nano materials and nano coating systems. In summary, these available resources give him a significant advantage in the field of avant-garde research.

Research Projects

Current projects

Development of a new rail maintenance technology by using laser cladding

The Government has made rail a national priority for investment. This project focuses on using laser cladding technology for the repair and preventative maintenance of passenger and heavy haul railway tracks in Australia. The outcome will ensure the structural integrity of rail infrastructure, which is critical due to the increasing freight demand.

Smart Equipment for Remote Monitoring of Isolated and Mobile Infrastructure.

The partners research involves the collection and assessment of data to determine the condition, maintenance strategies and risk of failure of plant in diverse areas such as transport, cargo and packaging, mining and power. Recent advances in data processing, computing and telemetry mean that it is now possible to actually install small and rugged data acquisition equipment on remote infrastructure or mobile plant. This equipment can acquire, condition and process the signals and use wireless telemetry to transmit the data for remote assessment. The proposed infrastructure will enable the partners research to be extended to these challenging applications.

Life Extension of Equipment Suffering Environmentally-Assisted Cracking: An Innovative Approach to Mitigation by Engineering of Materials in Service

Environmentally-assisted cracking (EAC) represents a serious threat to infrastructure exposed to caustic and chloride environments in process, marine, energy and chemical industries in Australia. Despite extensive research, there is no consensus mechanism for EAC. This project will investigate a fresh approach to life extension of in-service equipment suffering EAC, by developing and testing a mitigation measure reasonably independent of the EAC mechanisms. The task includes development of a consolidated strategy based on: accurate determination of the fundamental parameters for crack propagation, and in-situ thermomechnical treatment for local manipulation of material at and ahead of crack-tip, in order to retard/stop crack propagation.

Characterisation and Mitigation of Caustic Cracking: A Safety and Maintenance Concern in Alumina and Pulp-and-Paper Processing

Cracking due to synergism of tensile stress and caustic solutions (i.e., caustic cracking) is a major maintenance and safety concern in alumina and pulp-and-paper industries where vessels and pipe-work often encounter aggressive caustics at elevated temperatures and pressures. Caustic cracking is very sensitive to solutions chemistry and alloy variables, both of which vary considerably across and within the two industries, contributing to the inconsistency of plant experience with the handbook cracking susceptibility data (generated through simplistic tests). This project will develop an effective mitigation based on improved damage model, taking into account the mechanistic understanding of the role of solution chemistry and temperature.
