Symposium Technical Description
Instabilities are important features of many of today’s engineered materials, especially soft materials, and structures. Often instabilities represent failure of a material or structure, and thus it is important to identify and understand the types and behavior of instabilities that can occur in a given application area. More recently scientists and engineers have been taking advantage of the presence of instabilities in order to design materials and structures that have advantageous properties. This symposium will aim to bring together top researchers interested in the science of bifurcation and stability, from a broad variety of application areas within the context of solids and structures, in order to exchange knowledge and ideas on theory and experimentation in this vital and timely area of investigation.
