On the use of multiple layer thicknesses within laser powder bed fusion and the effect on mechanical properties (2021)
Journal Article

Laser Powder Bed fusion is capable of rapid production of parts, from conception, compared with traditional manufacturing methods. This said, the time taken to fabricate a single part can still be significant – typically many hours. Processing thicke...

A computationally efficient method for the prediction of fretting wear in practical engineering applications (2021)
Journal Article

A method for simulating fretting wear using the Modified Simplex Method for a contact solution has been developed. The initial separation between two contacting bodies was used as an input to solve the contact force distribution. An average cycle pre...

Thermomechanical fatigue life due to scatter in constitutive parameters (2021)
Journal Article

For critical component application, such as aerospace turbine rotors, it is imperative to be able to make accurate in-service material behaviour and component life predictions for both design and monitoring of component life. The development of such... Read More about Thermomechanical fatigue life due to scatter in constitutive parameters.

Small specimen techniques for estimation of tensile, fatigue, fracture and crack propagation material model parameters (2021)
Journal Article

Small specimen mechanical testing is an exciting and rapidly developing field in which fundamental deformation behaviours can be observed from experiments performed on comparatively small amounts of material. These methods are particularly useful whe... Read More about Small specimen techniques for estimation of tensile, fatigue, fracture and crack propagation material model parameters.

Machine learning to determine the main factors affecting creep rates in laser powder bed fusion (2021)
Journal Article

There is an increasing need for the use of additive manufacturing (AM) to produce improved critical application engineering components. However, the materials manufactured using AM perform well below their traditionally manufactured counterparts, par...

Multi-laser scan strategies for enhancing creep performance in LPBF (2021)
Journal Article

Laser Powder Bed Fusion (LPBF) enables complex structures to be manufactured, which is attractive to industries where augmented service performance can be achieved. However, the build time of LPBF can be slower than traditional manufacturing processe... Read More about Multi-laser scan strategies for enhancing creep performance in LPBF.

The creep behaviour of nickel alloy 718 manufactured by laser powder bed fusion (2021)
Journal Article

Components manufactured by laser powder bed fusion (LPBF) are limited by their performance for use in critical applications. LPBF materials have microstructural defects, such as suboptimal grain size and morphology, and macroscale anomalies, such as...
