Abstract:
Prestrained plates are slender materials that develop internal stresses
at rest, deform out of plane even without external forces, and exhibit
nontrivial 3d shapes. Bilayer plates are slender structures made of two
materials that react differently to environmental (thermal, electrical
or chemical) actuation. In both cases the plates can exhibit large
bending deformations that are geometrically nonlinear. We present
reduced nonconvex models, develop variational formulations, and design
local discontinuous Galerkin methods (LDGs). Moreover, we prove Gamma-
convergence of the discrete energies and analyze discrete gradient
flows for the computation of minimizers that provide control of the
metric defect. We document the performance of the LDG methods with
several insightful simulations.
