Transformation of CTOD δ5 to CTOD δBS and J-integral for 3PB- and CT-specimens

Engineering Fracture Mechanics, 1999
Abstract A two-region empirical formula is proposed for the transformation of crack tip opening displacement (CTOD) δ 5 to the standard CTOD δ BS and the J -integral. Coefficients of the approximation are fitted to data sets of three-dimensional elastic–plastic finite element solutions for plane side and side-grooved three-point bend and ...

A Proposal for Two Characteristic Ratios of ASTM-CTOD to BS-CTOD

Materials Science Forum, 2010
There have been two different CTOD calculations, geometric CTOD calculation in BS7448 and J-based conversion in ASTM E1290 since the ASTM International revised E1290 in 2002, and it is useful to transform one CTOD into the other CTOD. In this study, analytical and experimental investigations into the ratio of ASTM E1290-CTOD to BS7448-CTOD were carried

Low cycle fatigue analysis of CTOD under variable amplitude loading for AH-32 steel

Marine Structures, 2019
The present work aims to investigate the fatigue crack growth behavior of AH-32 steel with the experimental application of CTOD. A series of fatigue crack growth experiments on AH32 steel were conducted by a constant amplitude loading with a single/two ...

Proposal for a new CTOD calculation formula

Engineering Fracture Mechanics, 2016
Abstract A new CTOD calculation method is investigated in this work, considering the variation of crack tip blunting due to strain hardening. The calculation formula is constructed assuming that CTOD 45FEM based on three-dimensional elasto-plastic FEM is the target CTOD to be calibrated. A new factor f is introduced to correct the plastic term. In

J and CTOD Based Tensile Strain Capacity Prediction for Pipelines with a Surface Crack in Girth Weld

Journal of Pressure Vessel Technology, 2021
Long-distance pipelines for the transport of oil and natural gas to onshore facilities are mainly fabricated by girth welding, which has been considered as a weak location for cracking.
