Plastic collapse loads Pc and CTODs of a cracked Circular Hollow Section (CHS) T-joint

2012
The FailureAssessment Diagram (FAD) is an accepted approach in assessing the structural safety and integrity of any cracked tubular joint. In order to extend its application to a more complex geometry of any cracked Circular Hollow Section (CHS) tubular T-joint, there are three major challenges needed to be overcome; firstly there is a need to validate

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.

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 ...

Effects of Weld Strength Mismatch on J and CTOD Estimation Procedures for SENT Fracture Specimens Based on Plastic Eta-Factors

Volume 3: Materials Technology; Jan Vugts Symposium on Design Methodology of Offshore Structures; Jo Pinkster Symposium on Second Order Wave Drift Forces on Floating Structures; Johan Wichers Symposium on Mooring of Floating Structures in Waves, 2011
This work focuses on the evaluation procedure to determine the elastic-plastic fracture toughness J-integral and CTOD based upon the η-method for welded SENT fracture specimens with clamped ends. The primary objective is to gain additional understanding on the effect of weld strength mismatch on estimation techniques to determine J and CTOD fracture ...

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.
