Sulla storia degli studi di frattura in Italia
Journal Title: Frattura ed Integrità Strutturale - Year 2007, Vol 1, Issue 1
Abstract
La storia degli studi sulla frattura è inestricabilmente connessa con il progresso della tecnologia. All'inizio pochissimo fu scritto. Dobbiamo riconoscere a Leonardo e Galileo il merito di essere stati fra i primi a scrivere su questo problema e sui modi di misurare e prevedere carichi di rottura. Più tardi, scienziati italiani si distinsero nel tentativo di stabilire leggi sulla resistenza dei materiali e sui criteri di rottura sotto sforzi multipli. In questa memoria si descrivono i lavori degli scienziati italiani dei secoli scorsi e si confrontano con i lavori di altri scienziati europei del passato.

Prediction of the critical stress to crack initiation associated to the investigation of fatigue small crack
Fatigue design is of vital importance to avoid fatigue small crack growth in engineering structures. This study shows that the critical fatigue design stress can be defined below the usual endurance limit, conside...
Multi-purpose fatigue sensor. Part 1. Uniaxial and multiaxial fatigue
The paper describes the key principles and results of preliminary experiments aimed at the development of new technique for the fatigue life prediction under conditions of biaxial cyclic tension. The foundations o...
Critical plane approach to multiaxial variable amplitude fatigue loading
A new critical plane approach based on the modified Manson-Coffin curve method (MMCCM) is presented in this paper for predicting fatigue lifetime under variable amplitude (VA) multiaxial fatigue loading. The crit...
Role of the microstructure on the mechanical properties of fully pearlitic eutectoid steels
This paper analyses how the microstructure of an eutectoid pearlitic steel affects its conventional mechanical properties (obtained by means of a standard tension test) and the associated micromechanisms of fract...
Fatigue life prediction of casing welded pipes by using the extended finite element method
The extended finite element (XFEM) method has been used to simulate fatigue crack growth in casing pipe, made of API J55 steel by high-frequency welding, in order estimate its structural integrity and life. B...
