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.

Implementation of Recent Advances in Fracture Toughness Testing to Investigate Tearing Resistance of Heat-Resistant Steel 14MoV6-3 [PDF]

Archives of Metallurgy and Materials
Since WWII, progress has been made in understanding how materials fail and how to prevent such failures. In this work, the newly standardized Single Edge Notch Tension (SENT) specimen is used to assess the ductile tearing resistance of 14MoV-3 steel ...

The fatigue crack growth behavior of hydrogenated 9Cr‐1Mo steel: An experimental and numerical study

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 5, Page 1677-1695, May 2024.
Abstract This research investigates the fatigue crack evolution in P91 steel through experiments and extended finite element method (XFEM) simulation for as‐received and hydrogenated conditions. Hydrogen pre‐charging is performed using a constant current electrochemical method in 1 M sulfuric acid solution.

A Numerical Study of the Effect of Isotropic Hardening Parameters on Mode I Fatigue Crack Growth

Metals, 2020
The consideration of plastic crack tip opening displacement (CTOD, δp), as a crack driving force has given us the opportunity to predict fatigue crack growth (FCG) rate numerically, and, therefore, to develop parametric studies focused on the effect

Calibrating an adaptive cohesive zone model to simulate ductile crack propagation in structural steel under cyclic loading

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 2, Page 319-343, February 2024.
Abstract A procedure is outlined for calibrating a finite element model to simulate ductile cracking that employs a continuum damage criterion for ductile fracture initiation, termed the Stress Weighted Ductile Fracture Model, with an Adaptive Cohesive Zone method to simulate crack propagation.
