A polyconvexity condition in dimension two
Published online by Cambridge University Press: 14 November 2011
Extract
We state a necessary and sufficient polyconvexity condition in R2X2 for functions of class C1. This condition is applied to f(X) = |X|2(|X|2 −2 det X) for obtaining a convex representation in R2X2 x R.
