Software

  • Origami Cylinder GUI One application of engineering origami, is the use of origami fold patterns to compactly inflatable cylindrical booms for deployable space structures. As part of work on DeployTech I developed a small design tool in Matlab to explore different variations of fold patterns and assess their deployment strains: Origami Cylinder GUI.

Thomson & Tait Twisting Ring

As part of an upcoming paper 'On Zero Stiffness' we did some finite element simulations of the Thomson & Tait twisting ring. Take an initially straight rod with uniform bending stiffness, and bend it arbitrarily (but elastically) along its length. In this deformed configuration any twisting of the rod along its centroidal axis requires no torque, and the structure thus has zero stiffness. The explanation is immediately intuitive: there exists no preferential bending axis and thus any twisted orientation of the rod will have identical strain energy. This example was first described by William Thomson (later known as Lord Kelvin) and Peter Guthrie Tait in their 1867 Treatise on Natural Philosophy.

The mechanical behaviour is markedly different if an initially curved rod is subjected to the same loads, and a ring will deform into a saddle-shaped configuration.

Research Tools

MiKTeX
MiKTeX is the de facto standard LaTeX installation for Windows, and many LaTeX-related applications rely on its presence.
JabRef
JabRef is a reference manager, using the BibTeX bibliography format. It allows for easy management of your references and corresponding files, and allows for a wide range of export options.
Sublime Text 2
Sublime Text is a full-featured text editor; I haven't even scratched the surface of its capabilities, but already love it for its powerful features, clean UI and distraction-free full-screen mode.
DeTeXify
Tired of looking up the appropriate symbols for LaTeX? Just sketch the symbol you're looking for, and this app returns the desired code.
Export_Fig
This set of scripts provides superior export options for Matlab figures, into a range of file formats.
