As a specific example, the classical expression of the path-independent J-integral for elastic materials undergoing small deformations will be derived.engCopyright © 2025 Sage Publications, © The Author(s)Attribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Energy release rateJ-integralConfigurational forcesHyperelasticitySt. Venant-Kirchhoff materiallinear elasticityjournal articleopen access10.1177/10812865251401244
