Embrittlement Cutting of Structural Steel and Alloys - SRPe NMIS-IDP


Project Description

There are a number of well-established cutting techniques, such as laser, waterjet, plasma, saw, shear and explosive, which are widely used for the cutting of structural steels. However, these methods have their own limitations in terms of the thickness and size of the workpiece, the shape and environment of the cut (e.g. in-air or underwater). They also have different performance measures in terms of the cutting cost, speed, precision, quality and energy consumption. Most of the abovementioned techniques, either directly or with some modifications, are used for underwater cutting (i.e. high speed water jet, diamond wire saw cutting, flame cutting, oxy-arc cutting, plasma cutting, consumable electrode water jet cutting and underwater laser cutting, and explosive cutting techniques including bulk explosive charges, configured bulk charges, and cutting charges). Underwater cutting has a number of challenges as compared to in-air cutting: the safety of the operation becomes of more concern, particularly as the depth of water increases where there exists high safety risks to personnel, the cost increases exponentially with the cutting time (preparation and cutting operation) and the accessibility is normally an issue (e.g. due to marine growth on structure and cutting below the seabed). Development of a new cutting technique applicable to both in-air and underwater cutting of steel workpieces/ structures, which is cheaper, faster, safer and less energy consuming is a research challenge. This project is aimed at the development of a new steel cutting technique for in-air and underwater applications based on an innovative concept. The project is funded by Industry and the Scottish Funding Council through SRPe NMIS Industry Doctorate Programme.

The successful candidate should have, or expect to obtain a UK Honours Degree at 2.1 or above (or equivalent) in Mechanical Engineering and is expected to have a strong background in analytical heat & mass transfer analysis as well as some experience of using relevant engineering software tools for numerical analysis (FE and CFD) of multi-physics problems.
