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…

How do imperfections cause asymmetry in elastic snap-through?
Andrea Giudici, Weicheng Huang, Qiong Wang +4
A symmetrically-buckled arch whose boundaries are clamped at an angle has two stable equilibria: an inverted and a natural state. When the distance between the clamps is increased…

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…
