On the use of small ring testing for the characterisation of elastic and yield material property variation in additively manufactured materials (2020)
Journal Article

© 2020 Elsevier B.V. The present work introduces a small volume, high throughput testing method that may be used to quickly, and with high spatial fidelity, investigate local material properties in additively manufactured materials. A case study appl... Read More about On the use of small ring testing for the characterisation of elastic and yield material property variation in additively manufactured materials.

Experimental and numerical investigation of interface damage in composite L-angle sections under four-point bending (2020)
Journal Article

© The Author(s) 2020. Curved laminates in aero-structures, such as the L-angle sections where webs and flanges meet, are prone to delamination due to high interlaminar stresses in these regions. Some efforts to investigate delamination in these struc... Read More about Experimental and numerical investigation of interface damage in composite L-angle sections under four-point bending.

DevTMF – Towards code of practice for thermo-mechanical fatigue crack growth (2020)
Journal Article

© 2020 Elsevier Ltd The current paper presents work on identification and evaluation of a range of factors influencing accuracy and comparability of data generated by three laboratories carrying out stress-controlled thermo-mechanical fatigue crack g...

The prediction of crack propagation in coarse grain RR1000 using a unified modelling approach (2020)
Journal Article

© 2020 Elsevier Ltd The polycrystalline nickel-base superalloy RR1000 is used as turbine rotor material in Rolls-Royce aero engines and has to withstand a wide variety of load and temperature changes during operation. In order to maximize the potenti... Read More about The prediction of crack propagation in coarse grain RR1000 using a unified modelling approach.

Potential difference methods for measuring crack growth: A review (2020)
Journal Article

© 2020 Elsevier Ltd Non-destructive testing techniques are widely applied in industry for the evaluation of quantities of interest without inflicting additional damage accumulation. Crack detection and monitoring is a prime example of where non-destr... Read More about Potential difference methods for measuring crack growth: A review.

A viscoelastic – viscoplastic material model for superalloy applications (2020)
Journal Article

© 2020 Elsevier Ltd An understanding of rate dependency over a wide range of time scales is vitally important in approximating the transient response of critical components operating in extreme environments. Many examples of viscoplastic model formul... Read More about A viscoelastic – viscoplastic material model for superalloy applications.

Bayesian Reconstruction of Goal Orientated Error Fields in Large Aerospace Finite Element Models (2020)
Conference Proceeding

A major difficulty in the mechanical simulation of large aerospace structures is the multi-scale nature of modern designs due to, at least in part, the increased use of composite materials. "Thin" materials are typically idealised by shell elements i... Read More about Bayesian Reconstruction of Goal Orientated Error Fields in Large Aerospace Finite Element Models.

The effect of phase angle on crack growth mechanisms under thermo-mechanical fatigue loading (2020)
Journal Article

© 2020 Elsevier Ltd The current paper describes TMF crack growth behaviour in an advanced nickel-based superalloy. Changes in behaviour are examined which occur as a function of the phase angle between applied stress and temperature. The fractography...
