Description

(a) MICROFORMING ANALYSIS: form rolling of various geometrical shaped grooves on wire in the sub-millimetre range with particular emphasis on the 'size effect' as parts reduce in dimensions. Elastoplastic FEA is used to predict the material flow and the occurrence of likely internal defects in the miniature parts due to residual tensile stresses. (b) FRICTION STIR WELDING: experimental and viscoplastic FEA of Friction Stir Welding of 2024 aircraft fuselage panels. The experimental work involves the production of butt joints while the viscoplastic FEA is being used to simulate the material flow, temperature distribution and stress distributions within the welded sheets. (c) DEFORMATION BEHAVIOUR OF ALUMINIUM METALLIC FOAMS: experimental and elastoplastic FEA of the deformation behaviour of aluminium metallic foams subject to compression, bending, impact and penetration tests. (d) METALFORMING SIMULATIONS: Optimisation of the cold forging sequences used for the manufacture of high strength aerospace components. The work involves elastoplastic FEA simulations of the flow of the workpiece material and the stresses induced in the forging tooling during combined forging/extrusion operations on difficult to form materials. The use of elastoplastic FEA for the optimisation of the design of the tooling used in cold forming processes. (e) FORM ROLLING: experimental and FE analysis of macro Form Rolling process used in the production of grooves and other complex features on the shanks of high strength aerospace fasteners. This work involves the optimisation of the tool design process in an effort to reduce lengthy and costly physical prototyping. (f) SHEET FORMING SIMULATIONS - (A) ANALYSIS OF RIVETED JOINTS: Elastoplastic FEA and experimental analyses of the behaviour of riveted 2024 aluminium and GLARE sheets subjected to static and dynamic loading. (b) DENTING OF AIRCRAFT PANELS: experimental and elastoplastic FEA of the deformation behaviour and resulting residual stresses induced in 2024 aircraft fuselage panels due to indentation by various shaped indenters - e.g. hail; baggage trucks, spanners, etc
