Stiffness tailoring in sinusoidal lattice structures through passive topology morphing using contact connections (2023)
Journal Article

Structures with adaptive stiffness characteristics present an opportunity to meet competing design requirements, thus achieving greater efficiency by the reconfiguration of their topology. Here, the potential of using changes in the topology of plana... Read More about Stiffness tailoring in sinusoidal lattice structures through passive topology morphing using contact connections.

Tuning of compliant composite shell structures for assisted living (2022)
Presentation / Conference Contribution

The Office for National Statistics’ 50-year forecast predicts that the over sixty-five population of the UK will increase by 8.6 million [1], reflecting a world-wide trend towards ageing populations. Reduced mobility is commonplace within this demogr... Read More about Tuning of compliant composite shell structures for assisted living.

Characterising the transformative shear response of cellular lattices when subject to topological reconfiguration (2022)
Presentation / Conference Contribution

Demand for lightweight, adaptive and re-configurable structures is increasing in many fields such as space and robotics, encouraging designers to develop morphing lattice structures [1]. Changes in topology of lattice-like structures alters their eff... Read More about Characterising the transformative shear response of cellular lattices when subject to topological reconfiguration.

Morphing hexagonal frameworks (2022)
Presentation / Conference Contribution

Topology morphing lattice structures (2021)
Presentation / Conference Contribution

Planar cellular lattice structures subject to axial compression may undergo elastic bending or buckling of the unit cells. If sufficient compression is applied, the columns of adjacent cells make contact. This changes the topology of the lattice by e... Read More about Topology morphing lattice structures.

From shear centre to eigenwrenches (2021)
Journal Article

In the field of mechanism design, the behaviour of compliant shell mechanisms is commonly characterised via the eigenscrew decomposition of their spatial stiffness matrix. Recent developments have included the design of compliant shell mechanisms mad... Read More about From shear centre to eigenwrenches.

Topology morphing composites - A new route for tailored elasticity? (2021)

Exploring adaptive behavior of non-linear hexagonal frameworks (2020)
Journal Article

© Copyright © 2020 O'Donnell, Towes, Groh and Chenchiah. Non-linear structural responses offer a rich design space that can be integrated into the development of novel (meta)-materials to enable transformative capabilities. By exploiting robust, repe...

Reconsidering laminate nonsymmetry (2020)
Journal Article

Nonsymmetric laminates are commonly precluded from composite design due to perceptions of reduced performance arising from in- and out-of-plane coupling. This coupling introduces warpage during cure—leading to raised stresses, together with diminishe... Read More about Reconsidering laminate nonsymmetry.
