| Abstract: |
| Homogenization aims at deriving effective models for functionals or PDEs with highly oscillating spatial dependence. A major problem is to understand the asymptotic behavior of functionals with periodic/stationary integrands in the context of nonlinear elasticity, where typically constraints on the determinant of the gradient pose a substantial problem. After a short introduction to the subject, we show that the standard multi-cell formula used in the case of convex growth provides an upper bound for the Gamma-limit for a large class of functionals modeling incompressible materials with periodic structure. Ongoing work with Mathias Schäffner. |
