Numerical evaluation of plasticity induced crack closure in 3D structures
Procedia Structural Integrity, 2019 Abstract Fatigue growth of the crack may be retarded as a consequence of the fatigue crack closure occurrence. Complete understanding of the closure process and ability of its accurate assessment is in best interest of scientific and engineering community. In this paper, three-dimensional numerical model of M(T) specimen with straight crack front was

Analytical and numerical modelling of plasticity‐induced crack closure in cold‐expanded holes
Fatigue & Fracture of Engineering Materials & Structures, 2008 ABSTRACTThe aim of this research was the development of an analytical model for plasticity‐induced fatigue crack closure for cold expanded holes. This paper extends Nowell's plane stress model of plasticity‐induced crack closure for a plate with a circular hole and two radial symmetric cracks.

Can Delta Keff be assumed as the driving force for fatigue crack growth?
Fracture and Structural Integrity, 2015 This work raises some new questions about the validity of blindly assuming that Elber’s effective stress intensity factor is the actual fatigue crack driving force, and that as so it can be used to explain all load sequence effects on fatigue crack ...

An Evaluation of Plasticity-Induced Crack Closure Concept and Measurement Methods [PDF]
, 1999 An assessment of the plasticity-induced crack closure concept is made, in light of some of the questions that have been raised on the validity of the concept, and the assumptions that have been made concerning crack-tip damage below the crack-opening stress.

A numerical analysis of the plastic wake influence on plasticity induced crack closure
, 2017 Fatigue crack closure has been studied by means of finite element method since long time ago. Most work has been performed considering bi-dimensional models. Lately, the use of threedimensional models has been extended. Nevertheless, the methodology employed has been taken from that developed for bi-dimensional cases.
