heal.abstract	The mechanical behaviour of a soft-shellstone, the so called conchyliates, is studied here. Series of experiments were conducted with specimens obtained both from recent excavations and ancient blocks from the Olympia site. The mechanical properties were found to depend on the age of the material as well as on the point of the excavation. This observation and the failure mode indicated that to model the behaviour of conchyliates a Continuum Fracture Mechanics theory should be adopted, according to which the axial displacement rather than the strain is the parameter better describing the post failure behaviour under the formation of a perplex set of fractures. The agreement between theoretical predictions and experimental evidence was satisfactory for the case of newly excavated material. A recently developed honeycomb crushing model is shown to describe better the behaviour of ancient material, for which the failure mode was combination of cracking and localization of deformation.	en
