Composite crack profile model for CTOD determination III: An experimental application to elastic-plastic crack growth situations

Engineering Fracture Mechanics, 1987
Abstract A composite crack profile (CCP) model has been applied for the evaluation of CTOD in the elastic-plastic crack growth situations prevailing in a structural steel. The results have been compared with the ones obtained by conventional method (using plastic hinge model such as Wells etc.) The CTOD-Resistance Curves (δR-curves) have also been ...

An Elastic-Plastic Finite-Element Analysis of the J-Resistance Curve Using a CTOD Criterion

1988
The tentative test procedure for determining J-R curves (crack-growth resistance curves based on the J-integral) on compact and three-point bend specimens showed a discrepancy between specimen types: the bend specimen gave a higher J-R curve than the compact specimen.

Plasticity-Induced Crack Closure Under Thermomechanical Fatigue Loading: Influence of Phase Relationship and Plasticity Model on Crack Closure, Ctod, Ratcheting and Numerical Stability

In this work, plasticity-induced crack closure is studied under strain-controlled in-phase and out-of-phase thermomechanical fatigue (TMF) loading using the finite element method. The influence of the TMF phase, the applied strain ratio and the material model on the crack opening stress and the crack tip opening displacement is investigated. Therefore,

The Analysis of the Crack Tip Opening Displacement (CTOD) and the Magnitude of the Plastic Zone around a Crack Tip based on Dugdale's Strip Yield Model and the Estimation of its Reliability

1994
The article deals with analytical determination of stresses and displacements and some other fracture mechanics parameters, such as: the crack tip opening displacement (CTOD) and the magnitude of the plastic zone around a crack tip, in thin infinite cracked plates.
