Numerical predictions of U-notched sample failure based on a discrete energy argument
Kodsi (2016) proposed a criterion for isotropic, linear elastic media in a brittle state applicable to both sharp and blunt notches. Fracture toughness and material strength are the only parameters required to operate the criterion. This paper provides a formulation of the criterion speci c to blunt notches and further examines the capability of the criterion for samples weakened by U-notches. Predictions are compared to signi cant experimental results from U-notched samples that were subject to mixed-mode fracture. Good agreement is demonstrated, justifying and substantiating the theory.
