Elastoplastic analysis of cracked Aluminum plates with a hybrid repair technique using the bonded composite patch and drilling hole in opening mode I

open access: yesFracture and Structural Integrity, 2020
The objective of this study is to analyze the performance of composite bonding repair, hole drilling and the combination of the two techniques (hybrid repairs) by tensile tests and to show the interest of a hybrid repair versus to other processes.

Investigating Crack Resistance Behavior of Polypropylene Using J integral, J‐R Curve and Fractographic Analysis

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 8, Page 3404-3419, August 2026.
ABSTRACT In this study, the fracture response of polypropylene (PP) was assessed using J‐integral evaluation, J‐R curve construction, and fractography examination. J‐R and load–displacement curves were analyzed to determine critical loads and estimate J‐integral values based on standards established for polymer fracture testing, which led to the ...

Fatigue Crack Growth Behavior due to the Localized Compressive Deformation on Structural Steel

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1597-1609, May 2026.
ABSTRACT The localized compressive deformation (LCD) process was used to analyze the fatigue crack growth behavior of a high‐strength low‐alloy structural steel. Eccentrically loaded single‐edge crack tension specimens (ESE(T)) in accordance with standard ASTM E647 were precracked at a crack length of about 4 mm from the machined notch by applying a ...

Influence of Surface Flaw Interaction on Failure Assessment Diagram in the Framework of Fitness‐for‐Service Procedures

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1877-1894, May 2026.
ABSTRACT This study investigates the influence of closely spaced surface‐flaw interaction on failure assessment diagrams (FADs) used in fitness‐for‐service evaluations, addressing the conservatism introduced when standards such as BS 7910 and API 579 recharacterize interacting flaws as a single bounding crack.

Design and Development of an Accessible Clip Gauge Extensometer for CMOD Measurement in Fracture Mechanics

open access: yesEngineering Reports, Volume 8, Issue 2, February 2026.
A low‐cost clip gauge extensometer for crack mouth opening displacement was developed from accessible procedures and materials. Accuracy and repeatability comparable to commercial devices were demonstrated in calibration and fracture tests, enabling reliable measurement in CT specimens for resource‐constrained laboratories.

Prediction and Experimental Validation of the Influence of T‐Stress on I–II Mixed‐Mode Fracture in Rock

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Traditional fracture criteria only consider the singular terms in the Williams expansion and neglect higher‐order term coefficients, resulting in significant discrepancies between predicted and measured values. To advance the understanding of rock fracture mechanisms, this study introduces a generalized maximum tangential stress (GMTS) criterion by ...

Fracture Assessment of Weld Joints of High-Strength Steel in Pre-Strained Condition

open access: yesApplied Sciences, 2019
Unstable fractures tend to occur after ductile crack initiation or propagation. In most collapsed steel structures, a maximum 15% pre-strain was recorded, at the steel structural connections, during the great earthquake of 1995, in Japan. Almost-unstable

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

open access: yesMetals, 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

Influence of Notch Geometry and Temperature on the Mechanical Properties of Al‐Mg Alloy Using Molecular Dynamics Simulations

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 11, Page 4769-4783, November 2025.
ABSTRACT At the near‐threshold regime, small irregularities on the surface can interact with the microstructure and affect the nucleation and propagation of cracks. Molecular dynamics is an effective methodology to investigate the damage evolution at this scale, and three types of defects, namely, triangular, rectangular, and crack, are examined.

Electrostatically Reinforced Double Network Granular Hydrogels

open access: yesAdvanced 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
