On short cracks that depart from elastoplastic notch tips [PDF]
Fracture and Structural Integrity, 2017 The behavior of short cracks that depart from elastoplastic notch tips is modeled to estimate the stresses required to initiate and to propagate cracks in notched structural components, and to evaluate the size of tolerable crack-like defects under ...

Fatigue crack surface area and crack front length: new ways to look at fatigue crack growth
MATEC Web of Conferences, 2018 This paper discusses the appropriateness of crack length as a reference dimension for fatigue damage. Current discussion on short crack versus long crack data is still divided between various approaches to model small crack growth.
