Surface integrity in metal machining - Part I: Fundamentals of surface characteristics and formation mechanisms (2020)
Journal Article

The surface integrity of machined metal components is critical to their in-service functionality, longevity and overall performance. Surface defects induced by machining operations vary from the nano to macro scale, which cause microstructural, mecha...

Design of a resonant Luneburg lens for surface acoustic waves (2020)
Journal Article

© 2020 In this work we employ additive manufacturing to print a circular array of micropillars on an aluminium slab turning its top surface into a graded index metasurface for surface acoustic waves (SAW). The graded metasurface reproduces a Luneburg... Read More about Design of a resonant Luneburg lens for surface acoustic waves.

Tailored elastic surface to body wave Umklapp conversion (2020)
Journal Article

© 2020, The Author(s). Elastic waves guided along surfaces dominate applications in geophysics, ultrasonic inspection, mechanical vibration, and surface acoustic wave devices; precise manipulation of surface Rayleigh waves and their coupling with pol...

Generation of graded porous structures by control of process parameters in the selective laser melting of a fixed ratio salt-metal feedstock (2020)
Journal Article

The demonstration of salt dissolution incorporated within laser powder-bed fusion fabrication processes has allowed the creation of complex porous structures without the need for sophisticated design algorithms. This serves to simplify the process, f... Read More about Generation of graded porous structures by control of process parameters in the selective laser melting of a fixed ratio salt-metal feedstock.
