Quasiconvex elastodynamics: weak-strong uniqueness for measure-valued solutions
journal contribution
posted on 2023-06-09, 12:12 authored by Konstantinos KoumatosKonstantinos Koumatos, Stefano SpiritoA weak-strong uniqueness result is proved for measure-valued solutions to the system of conservation laws arising in elastodynamics. The main novelty brought forward by the present work is that the underlying stored-energy function of the material is assumed strongly quasiconvex. The proof employs tools from the calculus of variations to establish general convexity-type bounds on quasiconvex functions and recasts them in order to adapt the relative entropy method to quasiconvex elastodynamics.
