An Automated Inverse Method to Calibrate Thermal Finite Element Models for Numerical Welding Applications (2019)
Journal Article
Walker, T. R., & Bennett, C. J. (2019). An Automated Inverse Method to Calibrate Thermal Finite Element Models for Numerical Welding Applications. Journal of Manufacturing Processes, 47, 263-283. https://doi.org/10.1016/j.jmapro.2019.09.021

Numerical modelling of welding processes is often completed using a sequentially coupled FE thermo-mechanical analysis to predict both the thermal and mechanical effects induced by the process. The accuracy of the predicted residual stresses and dist... Read More about An Automated Inverse Method to Calibrate Thermal Finite Element Models for Numerical Welding Applications.

The effect of frequency on both the debris and the development of the tribologically transformed structure during fretting wear of a high strength steel (2019)
Journal Article
Kirk, A. M., Shipway, P. H., Sun, W., & Bennett, C. J. (2019). The effect of frequency on both the debris and the development of the tribologically transformed structure during fretting wear of a high strength steel. Wear, 426-427(Part A), 694-703. https://doi.org/10.1016/j.wear.2018.12.035

It is well established that damage to the first bodies in fretting wear gives rise to a hard and brittle tribologically transformed structure (TTS) which can influence both wear and fatigue. While the existence and significance of TTS has been establ...

A holistic inverse approach based on a multi-objective function optimisation model to recover elastic-plastic properties of materials from the depth-sensing indentation test (2019)
Journal Article
Iracheta, O., Bennett, C., & Sun, W. (2019). A holistic inverse approach based on a multi-objective function optimisation model to recover elastic-plastic properties of materials from the depth-sensing indentation test. Journal of the Mechanics and Physics of Solids, 128, 1-20. https://doi.org/10.1016/j.jmps.2019.04.001

Recent years have seen an increased interest in the mechanical characterisation of materials via the inverse analysis of depth-sensing indentation data; however, at low-loads both the reaction forces measured by the instrument and the contact evoluti...

Debris development in fretting contacts: debris particles and debris beds (2019)
Journal Article
Kirk, A., Shipway, P., Sun, W., & Bennett, C. (2019). Debris development in fretting contacts: debris particles and debris beds. Tribology International, https://doi.org/10.1016/j.triboint.2019.01.051

In this study, the formation and destruction of compacted beds of oxidized debris particles are investigated. Fretting tests of steel specimens were conducted, employing a cylinder-on-flat geometry with displacement amplitude being varied. The debris...
