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

Electrostatically Reinforced Double Network Granular Hydrogels

Advanced Science, Volume 12, Issue 20, May 29, 2025.
Electrostatically reinforced double network granular hydrogels (DNGHs) with cartilage‐like fracture energy are introduced. An empirical model predicts the composition‐dependent fracture energy based on dissipation zone size, contact area, and inter‐particle adhesion energy. Thanks to their granular structure and the inter‐particle attraction, the DNGHs

An Experimental Study of Fracture Parameters of Concrete Produced With Basalt Aggregate by Peak‐Load Method

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.

Preliminary Evaluation of the Influence of Hydrogen on the Fracture Toughness of an X65 Gas‐Transmission Pipeline Steel

Advanced Engineering Materials, Volume 26, Issue 16, August 2024.
We measured two values of fracture toughness for X65 steel in air (KQ of 369 and 487 MPa√m$\sqrt{} \text{m}$) and two essentially American Society for Testing of Materials–valid values of fracture toughness of KJ1C of 150 and 189 MPa√m$\sqrt{} \text{m}$ for X65 subjected to in situ hydrogen charging thought to be equivalent to a hydrogen gas pressure ...

Effect of CNT filler and temperature on fracture toughness of epoxy composites reinforced with carbon fabric

Engineering Reports, Volume 6, Issue 8, August 2024.
In present research the fracture behavior of carbon fabric‐epoxy composites was evaluated with the addition of 0.1, 0.2, 0.5, and 0.75 weight percentages of carbon nano tubes at different temperatures. Abstract In present research the fracture behavior of carbon fabric‐epoxy composites (CE composites) was evaluated with the addition of 0.1, 0.2, 0.5 ...

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.

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.

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.
