It enables rigorous derivation of the integral formulas for the energy release rate in crack problems. Applying a technique of the shape sensitivity analysis, we formulate the shape derivative of potential energy as a variational problem with a parameter. Key tools of our abstract theory are a new parameter variational principle and the classical implicit function theorem in Banach spaces.", "revisions": [ { "version": "v1", "updated": "2008-06-20T19:21:02.000Z" } ], "analyses": { "subjects": [ "35J20", "74G65", "74R10" ], "keywords": [ "potential energy", "fracture mechanics", "shape derivative", "study general mathematical framework", "classical implicit function theorem" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0806.3449K" } } }
