Stiffness tailoring in sinusoidal lattice structures through passive topology morphing using contact connections (2023)
Journal Article
Sundararaman, V., O'Donnell, M. P., Chenchiah, I. V., Clancy, G., & Weaver, P. M. (2023). Stiffness tailoring in sinusoidal lattice structures through passive topology morphing using contact connections. Materials and Design, 226, https://doi.org/10.1016/j.matdes.2023.111649

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.

Characterising the transformative shear response of cellular lattices when subject to topological reconfiguration (2022)
Presentation / Conference
Sundararaman, V., O'Donnell, M., Chenchiah, I., & Weaver, P. (2022, July). Characterising the transformative shear response of cellular lattices when subject to topological reconfiguration. Paper presented at 11th European Solid Mechanics Conference, National University of Ireland Galway

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.

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

Topology morphing lattice structures (2021)
Conference Proceeding
Sundararaman, V., O'Donnell, M., Chenchiah, I. V., & Weaver, P. (2021). Topology morphing lattice structures. In Proceedings Series: ASME 2021 Conference on Smart Materials, Adaptive Structures and Intelligent Systems. https://doi.org/10.1115/SMASIS2021-67531

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

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.
