DOI: 10.1177/10812865251401244This work aims to derive an expression for the energy release rate for hyperelastic materials using the configurational force framework. As a specific example, the classical expression of the path independent J-integral for elastic materials undergoing small deformations will be derivedengCopyright © 2025, Sage Publications.
