We formulate a geometric theory of nonlinear morphoelastic shells that can model the time evolution of residual stresses induced by bulk growth. We consider a thin body and idealize it by a representative orientable surface. In this geometric theory, bulk growth is modeled using an evolving referential configuration for the shell (material manifold). We consider the evolution of both the first and second fundamental forms in the material manifold by considering them as dynamical variables in the variational problem.

Two postdoctoral fellow positions at Northeastern University are available immediately, focused on the analysis of the nonlinear behavior of structures and soft matter using computational mechanics and the development and analysis of active cellular structures, and biomimetic materials. The research will be carried out at the High Performance Materials and Structures Laboratory (http://www.hpmsl.neu.edu/).

Dear All! If it will be interesting
for you please look at my FEM-pack FASTRAN. This software was developed for
dynamic analysis of the thin-walled shell-type structures and includes:
preprocessor (only for view early-developed FEM-models), processor (fast sparse
solver) and postprocessor (for view calculation results). Your opinion will be
very interesting for me.

Please find attached a report on a comparison between ANSYS SHELL181 and SOLSH190 elements with particular emphasis on applicability to linear elastic sandwich panels.

Abstract:

The Fluid Dynamics and Solid Mechanics group at Los Alamos National Laboratory is currently seeking outstanding candidates to fill a post-doctoral research position in computational solid/structural mechanics.

The prospective candidate is expected to take part in the development of non-classical, global-local plate/shell finite elements for applications involving the response and/or failure of composite structures under severe dynamic loading conditions.
