A validated analytical-numerical modelling strategy to predict residual stresses in single-track laser deposited IN718 (2018)
Journal Article

Direct Energy Deposition (DED) is being increasingly used to repair high value components that have been damaged in-service. The uptake of DED and laser cladding operations for repair is inhibited by accurate modelling techniques. Often the repair pr...

An experimental and numerical investigation on the process efficiency of the focused TIG welding of Inconel 718 thick plates (2018)
Journal Article

A combined experimental and numerical approach was adopted to investigate the focused tungsten inert gas (TIG) welding process by producing bead-on-plate welds in Inconel 718 plates. Experimental investigations were carried out by means of thermocoup...

On the interaction between welding residual stresses: a numerical and experimental investigation (2018)
Journal Article

The interaction of weld induced residual stresses in an important issue for multi-pass and repair welding operations; effective prediction of the magnitude and location of peak residual stresses can lead to improved lifing predictions and greater und...
