| Abstract: | A new method to evaluate the J-integral in finite-element models is developed and implemented. It is shown that in contrast to well-known approaches, this method ensures the invariance of the J-integral in finite-element solution of linear and nonlinear problems Translated from Prikladnaya Mekhanika, Vol. 44, No. 12, pp. 70–82, December 2008. |
