On the anisotropy in the dry-sliding behaviour of a self-lubricating PTFE composite and the effects from surface texturing (2021)
Journal Article

In self-lubricating sliding contact facilitated with polytetrafluoroethylene (PTFE) composites, the anisotropy in tribological performance was often attributed to the oriented structures of the polymer. However, in this research, it is found that the... Read More about On the anisotropy in the dry-sliding behaviour of a self-lubricating PTFE composite and the effects from surface texturing.

Analytical model for predicting residual stresses in abrasive waterjet peening (2021)
Journal Article

Abrasive waterjet peening (AWJP) is a new mechanical surface treatment where particles are delivered by a waterjet to induce plastic deformation and achieve surface strengthening effects on a workpiece. Although fatigue strength can be improved by in... Read More about Analytical model for predicting residual stresses in abrasive waterjet peening.
