DESCRIPTION:Speaker: Stefan Neukamm\nhosted by Julian Fischer\nAbstract: On
 e of the main problems in homogenization of nonlinearly elastic composites
  is that long wavelength buckling prevents the possibility of homogenizati
 on by averaging over a single period cell. A careful convexification argum
 ent (that invokes a perturbation of the stored energy function by a Null L
 agrangian) combined with regularity theory for monotone systems shows that
  long wavelength buckling cannot occur for small loads. Based on this obse
 rvation we obtain a quantitative two-scale expansion for energy minimizers
  and we can discuss the linearization of periodic composites at strained e
 quilibrium states. The talk is based on a joint work with M. Schffner.
