The understanding of the failure mechanisms at the margin of the tuffaceous slab on which the ancient town of Orvieto rises entails a comprehensive study on the mechanical behaviour of the Orvieto tuff. The paper reports the preliminary results of the research. First, a description of the textural and mineralogical features which can influence the material behaviour is given. Then the yielding surface, the stress-strain behaviour and the influence of uniaxial and triaxial loading on static and dynamic elastic moduli are discussed.

Abstract
The understanding of the failure mechanisms at the margin of the tuffaceous slab on which the ancient town of Orvieto rises entails a comprehensive study on the mechanical behaviour of the Orvieto tuff. The paper reports the preliminary results of the research. First, a description of the textural and mineralogical features which can influence the material behaviour is given. Then the yielding surface, the stress-strain behaviour and the influence of uniaxial and triaxial loading on static and dynamic elastic moduli are discussed.File in questo prodotto:
