Numerical Strip-Yield Calculation of CTOD [PDF]
, 2007 Many existing methods to calculate CTOD can be costly and complicated, or apply only to particular configurations. A new numerical method for calculating CTOD was investigated.

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 10, Page 3858-3873, October 2024.Abstract There are two methods for determining the fracture energy (Gf) of hot mix asphalt (HMA) composites at intermediate temperatures: (i) load–crack mouth opening displacement (CMOD) and (ii) load–load line displacement (LLD) curves. The effects of these two methods on the Gf values of different HMA mixtures are investigated at different loading ...

THE NON-CONSTANT CTOD/CTOA IN CRACK PROPAGATION [PDF]
, 2004 Unlike the common belief that crack propagation behavior can be predicted successfully by employing fracture criteria based on a constant crack tip opening displacement or angle (CTOD/CTOA), this paper shows that the initially non-constant portion of the

A comparative study of various approaches for CTOD toughness evaluation
, 1990 A comparative assessment of various methods proposed for CTOD toughness evaluation has been made on two structural steels. CTOD values are obtained from experimental CMOD data by direct extrapolation as given by Wells' method, BS5762 etc.

Slip‐resistant connections subjected to freeze‐thaw cycles
Steel Construction, Volume 17, Issue 3, Page 155-163, August 2024.Abstract There are many examples of steel structures subjected to severe environmental conditions with bolted connections directly exposed to climatic agents such as steel bridges, mining transfer towers, wind towers etc. In this experimental research, non‐slip joints with M16 and M20 bolts have been studied. The specimens were subjected to fourteen 12

Computing the stress intensity factor range for fatigue crack growth testing at 20 kHz
Engineering Reports, Volume 6, Issue 6, June 2024.A comparative study on the computation of the SIF at 20 kHz load frequency. Results from different simulation procedures are presented and discussed. Abstract Inertia and damping influence the values of the stress intensity factors (SIFs) at high‐frequency loading and they must be included in computations.
