Abstract:
We present a classification of strict limits of planar BV homeomorphisms. The authors and S. Hencl showed in a previous work 6 that such mappings allow for cavitations and fractures singularities but fulfill a suitable generalization of the INV condition. As pointed out by J. Ball 3, these features are physically expected by limit configurations of elastic deformations. In the present work we develop a suitable generalization of the no-crossing condition introduced by De Philippis and Pratelli in 8 to describe weak limits of planar Sobolev homeomorphisms that we call BV no-crossing condition, and we show that a planar mapping satisfi es this property if and only if it can be approximated strictly by homeomorphisms of bounded variations
