Abstract
We consider a nonlinear traction boundary value problem for the Lamé equations in an unbounded periodically perforated domain. The edges lengths of the periodicity cell are proportional to a positive parameter δ, whereas the relative size of the holes is determined by a second positive parameter ε. Under suitable assumptions on the nonlinearity, there exists a family of solutions (Formula presented.). We analyze the asymptotic behavior of two integral functionals associated to such a family of solutions when the perturbation parameter pair (ε, δ) is close to the degenerate value (0, 0).File in questo prodotto:
