Enhancing the energy absorption of AlSi10Mg thin-walled tubes with internal lattice structure through laser powder bed fusion Open
Heat-treated aluminium thin-walled tubes combine efficient energy absorptive properties with low weight, making them common engineering structures for impact mitigation. Recently, the integration of foam cores within these structures furth…

A hybrid continuum-beam optimisation model: the virtual extensometer method for efficient optimisation of lattice materials Open
Additive manufacturing (AM) enables the fabrication of complex lattice structures that are infeasible with traditional manufacturing processes. These structures are typically implemented with constant cross-sectional strut elements; this s…

Ti–6Al–4V hybrid-strut lattice metamaterials: A design strategy for improved performance Open
Metal hollow-strut lattices manipulate the strut and node sections to achieve higher strength. Although these metamaterials have recently surpassed the structural efficiency of conventional solid-strut lattices of comparable density and to…

Additively Manufactured Functionally Graded Lattices: Design, Mechanical Response, Deformation Behavior, Applications, and Insights Open
Flora and fauna have evolved to distribute their structural mass efficiently in response to their environment. Inspired by this structural efficiency, functionally graded lattices (FGL) are an emerging subset of non-uniform lattices that e…
