EGS.Lab we are dedicated to the fundamental understanding of
the mechanics of thin objects and structures; including rods, plates
and shells. The large
displacements permissible in such configurations can give rise to
non-negligible geometric nonlinearities, even if its material
properties remain linear. Of interest
is also the coupling of the
elasticity of thin objects with other phenomena such as fracture,
adhesion, ﬂuid forces at liquid interfaces and ﬂow.
Examples of relevant applications range from
thin elements in
stretchable electronics and micro-actuators to large civil engineering
contexts such as domes, hypar roofs and borewell drilling.
The starting point of the investigations is
often through well
controlled experiments of desktop-scale model systems for which we take
advantage of advanced digital fabrication techniques. The final goal is
often the predictive
understanding of the large deformations of thin structures. Once a
theoretical framework has been developed and the underlying mechanics
rationalized, we then aim at implementing it at scale of the original
problem (small or large scale) towards practical applications.
A general overview of the
questions involving thin structures that interest us can be
found in the Journal
Club of iMechanica (June 2010),
in the Research
Group profile @ the Engineering Mechanics Institute (September 2011), the Journal
Club of iMechanica (October 2013) and MIT Spectrum (Spring 2014).
