Tensile And Low-cycle Compressive Tests On A
Natural Structural Stone

Abstract
The present work presents some first results of an experimental study in which samples
of a natural-occurring stone, called "leccese", were subjected to fatigue through low-
cycle tests in the presence of high compressive stresses. The specimens' behaviour
remains typical up to the last cycle, during which brittle failure occurs, with gradual
accumulation of permanent strains. Other tests by pure tension or compression
performed up to failure on samples previously subjected to a interrupted low-cycle
fatigue test, confirmed that during such fatigue cycles the damage process is
accompanied by meaningful variations in some significant mechanical parameters,
amongst which, the Young elastic modulus and tensile strength are particularly telling.
