Convenient method for estimation of JIC by CTOD.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1985 The JSME standard (S-001) for determination of JIC recommended to draw the blunting line or to measure the stretched zone width by an electron microscope. However, this procedure is taken trouble to measure these values. Following the British Standard BS5762, the CTOD value, Φi, at the onset of the ductile fracture is determined by using the CTOD ...

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.Limestone or river aggregates have been traditionally used as aggregates in ready‐mixed concrete from the past to the present. The depletion of these natural aggregates used in ready‐mixed concrete has led the concrete industry to investigate aggregate resources and search for alternative aggregates.

Application of CTOD in Atomistic Modeling of Fracture
Procedia Materials Science, 2014 AbstractIn atomistic modeling of fracture, most examinations are based on the Griffith energy, calculated from the surface energy, and the stress intensity factor derived from continuum mechanical formulations. Both approaches, however, reflect continuum mechanics and lack the direct connection to the atomistic crack tip mechanisms, and it is thus ...

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

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 ...

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.

Fatigue Crack Growth in Maraging Steel Obtained by Selective Laser Melting
Applied Sciences, 2019 Selective Laser Melting (SLM) is an additive manufacturing technology, ideal for the production of complex-shaped components. Design against fatigue is fundamental in the presence of cyclic loads, particularly for these materials which typically have ...

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
