Dear friends,
First of all, some information about the Publisher’s website, Gruppo Italiano Frattura (IGF). Now we have a new address (www.gruppofrattura.eu) and the website is based on Google Sites, offering many services (we will discover them all together in the next future!) and allowing to obtain a really high responsiveness of the website, being really independent on the device you use to surf the site. I hope you will appreciate this new approach.
Secondly some news about the recent activities organized by IGF. Although these last months were quite hard for the events organizers, IGF opened the 2020 with two successful events:
- The VCSI1 (1st Virtual Conference on Structural Integrity; in cooperation with the Greek, the Portuguese and the Serbian Fracture groups) that was held online on January 16, 2020 and, maybe, defined a new paradigm in the organization of low cost-high quality events. All the presentations and the discussions are available in the IGF YouTube channel (https://www.youtube.com/c/IGFTube) and the papers will be published in a Procedia Structural Integrity Issue.
- The MedFract1 (1st Mediterranean Conference on Fracture and Structural Integrity, in cooperation with the Greek fracture group), that was held in Athens (Greece) in February (26-28). In this case, we were able to face the problems created by the Covid-19 organizing some virtual sessions with remote speakers. Also in this case, all the presentations are available in the IGF YouTube channel (https://www.youtube.com/c/IGFTube) and the papers will be published in a Procedia Structural Integrity Issue.
Third, we are trying to “push” the YouTube channel we are using to publish the Visual Abstracts:

As you can see, as we have less than 100 subscribers, we can’t have a customized url. Please, join the channel!! In the Table of Contents now you can find the Visual Abstract url for each published paper.
Please, do not hesitate to send us your suggestions to further improve our journal. Very best,
Nanostructured adhesives may be defined as those materials whose elements imbedded in an epoxy matrix have dimensions in the 1 to 100 nm range. One of the most interesting aspects of ceramic nanoparticles is that their mechanical…
T joint is a widely used welding form. The welding deformation and residual stress produced during the welding process will affect the integrity and reliability of the structure. In this study, S355 low alloy steel was used as test…

Wavelet transforms are efficient tools for structural health monitoring (SHM) and damage detection. However, these methods are encountered with some limitations in practice. Thus, signal energy analysis is used as an alternative technique…
High Pressure Torsion (HPT) is a highly effective super-plastic deformation process for obtaining nano-materials with high performance mechanical properties. In view of its optimization, it is of paramount importance to evaluate the…
The main aim of this work is to predict the theoretical burst pressure of defective pipelines using different semi-empirical models and compare them with the results of the hydrostatic tests. A methodology was formulated with accounting…
Among different parts of a vehicle, the body is the main load-bearing component and as a result, its durability is critical. Fatigue analyses are typically divided into different categories, the quasi-static methods and the dynamic…
The present study is concerned with formulation of a model for the creep–fatigue crack growth rate prediction on the base of fracture damage zone concepts. It is supposed that crack growth rate can be determined by integration of damage…
Development in material science impose to use different materials in production. This causes a problem for joining different materials because traditional joining techniques such as welding could not overcome this problem in industries…
Gypsum is a soft rock with low strength and high propensity to plastic deformation. Its mechanical properties are relevant in a wide range of technical application (e.g. tunnel excavation, stability assessment of underground quarries, oil…
There are deficiencies associated with cold mix asphalts, specifically, cold recycled mix asphalts in comparison with hot mix asphalt or hot recycled mix asphalt such as higher moisture susceptibility. Moisture damage of asphalt mixtures…
Problems involving errors and uncertainties from the use of numerical and experimental responses of beams using optimization processes have been studied by many researchers. In this field, to simulate the real behavior of structures…
Fitness-for-service assessment of a cracked component intends to evaluate its remaining strength and remaining life to support the implementation of a maintenance plan. This research aims to develop a fitness-for-service assessment…
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…
C Composite materials are most often used for lengthier and thin structures susceptible to buckle. The optimization is often carried out taking into consideration the resistance to buckling and tensile loads for minimum displacement i.e…
Building crack monitoring is of great value to the judgment of building safety. In this study, the digital image processing technology was studied and applied to the monitoring of building cracks. Crack images were collected by CCD camera…

The thermal behavior in WAAM process is a significant cause for thermal stress. In this paper, a 3D model of a four-layer wall is built in ABAQUS software in order to investigate the thermal behavior in a carbon steel (ASTM A36) WAAM wall.…
Initiation and propagation of ductile fractures are a major consideration during the design of high-pressure pipelines. Consequences of a pipeline failure can be catastrophic thus structural integrity must be ensured over several decades.…
The goal of this work is to propose a general mechanism for hydrogen induced crack initiation in steels based on a microstructural study of multiple steel grades. Four types of steels with strongly varying microstructures are studied for…
