An iterative numerical approach to evaluate the variable friction coefficient of steel AMS5643 using ring compression tests (2023)
Journal Article

The coefficient of friction is an important variable that must be defined to allow the accurate prediction of the forming geometry and stresses involved in metal forming processes. Literature reports have shown that the coefficient of friction does n...

Exploring the potential for a FEA-based design of experiments to develop design tools for bulk-metal joining processes (2023)
Presentation / Conference Contribution

Over the last 20 years, finite element analysis (FEA) has become a standard analysis tool for metal joining processes. When FEA tools are combined with design of experiments (DOE) methodologies, academic research has shown the potential for virtual D...

Anomalous mechanical behaviour arising from framework flexibility (2023)
Book Chapter

This chapter describes in detail the framework of anisotropic elasticity to introduce exotic elastic and thermoelastic properties that are often prevalent and extreme in MOFs: negative linear compressibility (NLC), negative thermal expansion (NTE) an...

Negative Poisson's ratio: A ubiquitous feature of wood (2023)
Journal Article

Most materials contract laterally when stretched axially i.e. they have a positive Poisson's ratio. Negative Poisson's ratios (NPR, also auxetic) are largely limited to single crystals or to artificial meta-materials such as honeycombs, foams and com...

surfinpy: A surface phase diagram generator (2019)
Journal Article

A surface phase diagram is a graphical representation of the different physical states of a surface under different conditions. The surface represents the first point of contact between the material and the environment. Thus, understanding the state... Read More about surfinpy: A surface phase diagram generator.

Evidence of negative Poisson's ratio in wood from finite element analysis and off-axis compression experiments (2017)
Journal Article

© 2017 The microstructure of wood is highly anisotropic, which suggests that this material could exhibit unusual elastic properties. A few studies have suggested the possibility of auxeticity, or negative Poisson's ratio (NPR) in some wood samples. I...

Determination of the anisotropic elastic properties of rocksalt Ge2Sb2Te5 by XRD, residual stress, and DFT (2016)
Journal Article

© 2016 American Chemical Society. The chalcogenide material Ge2Sb2Te5 is the prototype phase-change material, with widespread applications for optical media and random access memory. However, the full set of its independent elastic properties has not... Read More about Determination of the anisotropic elastic properties of rocksalt Ge2Sb2Te5 by XRD, residual stress, and DFT.

Flexibility in MOFs: Do scalar and group-theoretical counting rules work? (2015)
Journal Article

© The Royal Society of Chemistry 2016. We investigate the ability of counting rules drafted from engineering to predict the flexibility or rigidity of bar-and-joint or body-and-joint assemblies representing metal organic frameworks. We show that whil... Read More about Flexibility in MOFs: Do scalar and group-theoretical counting rules work?.

A systematic typology for negative Poisson's ratio materials and the prediction of complete auxeticity in pure silica zeolite JST (2015)
Journal Article

© the Owner Societies 2015. Single crystals can commonly have negative Poisson's ratio in a few directions; however more generalised auxeticity is rarer. We propose a typology to distinguish auxetic materials. We characterise numerous single crystals...

Negative linear compressibility in common materials (2015)
Journal Article

© 2015 AIP Publishing LLC. Negative linear compressibility (NLC) is still considered an exotic property, only observed in a few obscure crystals. The vast majority of materials compress axially in all directions when loaded in hydrostatic compression... Read More about Negative linear compressibility in common materials.
