Transformation of BS7448-CTOD to ASTM E1290-CTOD
Volume 1: Codes and Standards, 2008Experimental and analytical investigations into Crack Tip Opening Displacement, CTOD, were conducted to demonstrate the relationship between BS7448-CTOD and ASTM E1290-CTOD. CTOD test results showed that ASTM-CTOD was occasionally much lower than BS-CTOD both in single edge notch bend specimens and in CT specimens for low-strength structural steels ...

A Comparison Between BS7448-CTOD and ASTM E1290-CTOD in Linepipes
Volume 6: Materials Technology; C.C. Mei Symposium on Wave Mechanics and Hydrodynamics; Offshore Measurement and Data Interpretation, 2009ASTM E1290 previously used the plastic hinge model for the calculation of CTOD, but has changed its CTOD calculation to J-based conversion since 2002. In this study, the ratio of ASTM-CTOD to BS-CTOD was analytically predicted and experimentally evaluated in linepipes. It was demonstrated that the CTOD ratio changed according to CTOD itself, and took a

Equivalent CTOD Ratio β for Engineering Assessment of CTOD Correction for Constraint Loss
Volume 1: Codes and Standards, 2008The critical CTOD δWP for structural components associated with plastic constraint loss in case of the brittle fracture over small-scale yielding condition can be corrected from CTOD fracture toughness δ by means of the “equivalent CTOD ratio β” defined as δ/δWP, which is based on the Weibull stress criterion. In this study, taking the case of specific

Outlier detection is a well studied problem in various fields. The unique challenges of wireless sensor networks such as limited bandwidth, memory, energy, and unreliable communi- cation make this problem especially difficult. Sensors can detect outliers for a plethora of reasons and these reasons need to be inferred in real time.

Experiences and test results of IWM concerning the fracture mechanics characterization of multipass submerged arc and manual metal arc welds in thick components of C-Mn, steel are described. The influences of materials, fabrication parameters and testing variables on the fracture toughness in terms of critical CTOD are discussed.

CTOD estimates of surface cracked wide plates in bending—II. Level-3 CTOD method
Engineering Fracture Mechanics, 1991Abstract The Welding Institute Level-3 crack tip opening displacement (CTOD) method was expanded to be applicable to plane strain (Plane-strain Level-3 CTOD method). The definition of the reference strain is a major source of uncertainty in the application of the Level-3 CTOD method.
