Abstract

In this brief note, we provide the failure stress of a solid containing a penny-shaped crack by means of Finite Fracture Mechanics. The solution is analytical up to the numerical root of the equation providing the finite crack growth increment. Results are discussed and compared with the ones provided by Linear Elastic Fracture Mechanics, by Theory of Critical Distances and by Cohesive Crack Model (with a Dugdale-type cohesive law).
