Mechanical Characterizastion of Mediterranean Yellow Tuff

Acronimo TUFO

Abstract Historical buildings represent surely critical structures, widely present in our cities and the behavior of constituent materials under high dynamic loads is absolutely fundamental to investigate the vulnerability of such structures under extreme dynamic events. The objective of the project is to study the effect of high dynamic loading conditions on a classical porous natural stone of Neapolitan area, namely Yellow Tuff, present in hundreds of historical buildings and monuments in Naples and other Mediterranean cities. Hence, a dynamic characterization was performed, through high strain-rate failure tensile tests. A wide range of strain-rate were investigated, from 10^-5 1/s to 50 1/s. Tensile failure tests were conducted, in the DynaMat laboratory on Yellow Tuff specimens, investigating in particular medium and high strain-rate. The obtained data were processed to obtain stress-strain relationships at different strain-rate and moisture content levels.
