Hello everyone, I'm trying to compute the effective elastic properties of a heterogeneous, linear and a bi-periodic system (i.e., left-right and top-bottom periodic displacement fields). To this system, I would like to apply a global shearing by prescribing the displacement field of the surfaces in the form of Dirichlet BCs. This seems slightly contradictory since a bi-periodic system doesn't have surfaces.
However, we can still think of the global shearing as an average surface displacement around which periodic fluctuations occur (the origin of such fluctuations is due to heterogeneous elastic properties). This is illustrated in the picture below. [image: bitmap.png] I would like to know which is the best way to do this in deal.II (I have tried with make_periodicity_constraints and interpolate_boundary_values, but the problem is that, as I explain before, we set apparently contradictory constraints). Thank you in advance. P.S.: suggestions of alternative procedures to achieve the same goal are welcome. -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
