Analysis and Design of Kirigami-based Metallic Energy-Dissipating Systems (2025)
Journal Article
Khalilzadehtabrizi, S., Mohagheghian, I., & Walker, M. (2025). Analysis and Design of Kirigami-based Metallic Energy-Dissipating Systems. Thin-Walled Structures, 212, Article 113127. https://doi.org/10.1016/j.tws.2025.113127

Kirigami, the Japanese art of paper cutting, can be used to generate complex 3D shapes from 2D sheets. Kirigami structures can also be highly stretchable and accommodate extremely large strains from common materials, such as aluminium, which allow re...

Folding Auxetic Polygonal Kirigami Tubes (2024)
Journal Article
Walker, M. G. (2024). Folding Auxetic Polygonal Kirigami Tubes. Journal of Mechanisms and Robotics, 16(12), Article 121012. https://doi.org/10.1115/1.4065372

Tubular auxetic structures have wide-ranging applications including medical stents, collapsible energy absorbers, and novel fasteners. To accelerate the development in these areas, and open up new application directions, an expanded range of design a... Read More about Folding Auxetic Polygonal Kirigami Tubes.

Non-invariant elastic moduli of bi-level architected lattice materials through programmed domain discontinuity (2023)
Journal Article
Sinha, P., Walker, M., & Mukhopadhyay, T. (2023). Non-invariant elastic moduli of bi-level architected lattice materials through programmed domain discontinuity. Mechanics of Materials, 184, Article 104691. https://doi.org/10.1016/j.mechmat.2023.104691

Effective elastic moduli of lattice-based materials are one of the most crucial parameters for the adoption of such artificial microstructures in advanced mechanical and structural systems as per various application-specific demands. In conventional... Read More about Non-invariant elastic moduli of bi-level architected lattice materials through programmed domain discontinuity.

Axisymmetric ridges and circumferential buckling of indented shells of revolution (2022)
Journal Article
Taffetani, M., & Walker, M. G. (2022). Axisymmetric ridges and circumferential buckling of indented shells of revolution. Physical Review E, 105, Article 065003. https://doi.org/10.1103/PhysRevE.105.065003

When poking a thin shell-like structure, like a plastic water bottle, experience shows that an initial axisymmetric dimple forms around the indentation point. The ridge of this dimple, with increasing indentation, eventually buckles into a polygonal... Read More about Axisymmetric ridges and circumferential buckling of indented shells of revolution.

Mitigation of blast effects through novel energy-dissipating connectors (2022)
Journal Article
Seica, M. V., Packer, J. A., Walker, M. G., & Gow, M. I. (2022). Mitigation of blast effects through novel energy-dissipating connectors. International Journal of Protective Structures, 13, 236-272. https://doi.org/10.1177/20414196221074058

Explosions generate overpressures that can cause irreparable damage to structures. For many buildings, especially critical infrastructure, continued operation after an explosive attack is essential. The use of energy-dissipating methods will enable t... Read More about Mitigation of blast effects through novel energy-dissipating connectors.

Mechanics of generically creased disks (2020)
Journal Article
Walker, M. G. (2020). Mechanics of generically creased disks. Physical Review E, 101(4), https://doi.org/10.1103/physreve.101.043001

Folded structures are often idealized as a series of rigid faces connected by creases acting as revolute hinges. However, real folded structures can deform between creases. An example of particular interest is a disk decorated by multiple radial crea... Read More about Mechanics of generically creased disks.

The flexural mechanics of creased thin strips (2019)
Journal Article
Walker, M., & Seffen, K. (2019). The flexural mechanics of creased thin strips. International Journal of Solids and Structures, 167, 192-201. https://doi.org/10.1016/j.ijsolstr.2019.03.016

Many structures in Nature and Engineering are dominated by the influence of folds. A very narrow fold is a crease, which may be treated with infinitesimal width for a relatively simple geometry; commensurately, it operates as a singular hinge line wi...

On the shape of bistable creased strips (2017)
Journal Article
Walker, M. G., & Seffen, K. A. (2018). On the shape of bistable creased strips. Thin-Walled Structures, 124, 538-545

We investigate the bistable behaviour of folded thin strips bent along their central crease. Making use of a simple Gauss mapping, we describe the kinematics of a hinge and facet model, which forms a discrete version of the bistable creased strip. Th...
