TY - GEN T1 - Duality based a posteriori error estimates for higher order variational inequalities with power growth functionals A1 - Bildhauer,Michael A1 - Fuchs,Martin A1 - Repin,Sergey Y1 - 2012/03/20 N2 - We consider variational inequalities of higher order with p-growth potentials over a domain in the plane by the way including the obstacle problem for a plate with power hardening law. Using duality methods we prove a posteriori error estimates of functional type for the difference of the exact solution and any admissible comparision function.
