Demoulini, D. M. A. Stuart and A. E. Tzavaras [Arch. Ration. Mech. Anal. 157 (2001)] that approximates the equations of three dimensional elastodynamics with polyconvex stored energy. We establish the convergence of the time-continuous interpolates constructed in the scheme to a solution of polyconvex elastodynamics before shock formation. The proof is based on a relative entropy estimation for the time-discrete approximants in an environment of Lp-theory bounds, and provides an error estimate for the approximation before the formation of shocks.", "revisions": [ { "version": "v1", "updated": "2014-08-04T21:14:46.000Z" } ], "analyses": { "subjects": [ "35L70", "74B20", "74H20" ], "keywords": [ "variational approximation schemes", "polyconvex energy", "convergence", "error estimate", "polyconvex stored energy" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1408.0820M" } } }
