Dalla frattura alla scienza dei metalli
Journal Title: Frattura ed Integrità Strutturale - Year 2008, Vol 2, Issue 4
Abstract
La frattura inizia ad essere considerata oggetto di studio da Leonardo da Vinci e trova in Vannoccio Biringucci ed in Galileo Galilei i precursori di un approccio scientifico al come e perchè si produce una rottura. Nell'arco di poco più di un secolo, il sedicesimo, si trovano i primi riferimenti scritti di esperienze e interpretazioni su cui lavorare: i limiti tecnologici e di conoscienza scientifica dei materiali allora disponibili hanno impedito una interpretazione soddisfacente del fenomeno della rottura. Sarebbero occorsi altri due secoli per collegare una relazione lineare, prima forza e deformazione, e poi tensione e deformazione

Damage propagation in a masonry arch subjected toslow cyclic and dynamic loadings
In the present work, the damage propagation of a masonry arch induced by slow cyclic anddynamic loadings is studied. A two-dimensional model of the arch is proposed. A nonlocal damage-plasticconstitutive law is ado...
