Significant weight savings in parts can be made through the use of additive manufacture (AM), a process which enables the construction of more complex geometries, such as functionally graded lattices, than can be achieved conventionally. The existing... Read More about Mechanical Properties of Ti-6Al-4V Selectively Laser Melted Parts with Body-Centred-Cubic Lattices of Varying cell size.

The creation of an object by selective laser melting (SLM) occurs by melting contiguous areas of a powder bed according to a corresponding digital model. It is therefore clear that the success of this metal Additive Manufacturing (AM) technology reli...

Nano-hardness and microstructure of selective laser melted AlSi10Mg scan tracks (2015)
Presentation / Conference Contribution
Aboulkhair, N. T., Tuck, C., Maskery, I., Ashcroft, I., & Everitt, N. Nano-hardness and microstructure of selective laser melted AlSi10Mg scan tracks. Presented at Industrial Laser Applications Symposium (ILAS 2015)

Selective laser melting (SLM) of aluminium alloys faces more challenges than other ongoing alloys such as stainless steels and titanium alloys because of the material’s properties. It is important to study single scan tracks if high density large par... Read More about Nano-hardness and microstructure of selective laser melted AlSi10Mg scan tracks.

Reducing porosity in AlSi10Mg parts processed by selective laser melting (2014)

In recent years, cohesive elements based on the cohesive zone model (CZM) have been increasingly used within finite element analyses of adhesively bonded joints to predict failure. The cohesive element approach has advantages over fracture mechanics... Read More about Modelling damage and failure in adhesive joints using a combined XFEM-cohesive element methodology.
