Mechanics of elliptical JKR-type adhesive contact
Andrea Giudici, Dominic Vella, Ian Griffiths
The classic Johnson Kendall Roberts (JKR) theory describes the short-ranged adhesive contact of elastic bodies, but is only valid for axisymmetric contact. A theory for non-axisymm…
Transient amplification of broken symmetry in elastic snap-through
Qiong Wang, Andrea Giudici, Weicheng Huang +4
A snap-through bifurcation occurs when a bistable structure loses one of its stable states and moves rapidly to the remaining state. For example, a buckled arch with symmetrically…
Curvature-driven instabilities in thin active shells
Andrea Giudici, John S. Biggins
Spontaneous material shape changes, such as swelling, growth or thermal expansion, can be used to trigger dramatic elastic instabilities in thin shells. These instabilities origina…
Large deformation analysis of spontaneous twist and contraction in nematic elastomer fibres with helical director
Andrea Giudici, John S. Biggins
A cylindrical rubber fibre subject to twist will also elongate: a manifestation of Poynting's effect in large strain elasticity. Here, we construct an analogous treatment for an ac…
Giant deformations and soft-inflation in LCE balloons
Andrea Giudici, John S. Biggins
We propose that ballooning can be controlled, enriched and amplified by using rubbery networks of aligned molecular rods known as liquid crystal elastomers (LCEs). Firstly, LCEs ar…
Ballooning, bulging and necking: an exact solution for longitudinal phase separation in elastic systems near a critical point
Andrea Giudici, John S. Biggins
Prominent examples of longitudinal phase separation in elastic systems include elastic necking, the propagation of a bulge in a cylindrical party balloon and the beading of a gel f…
