shape of the notch

Περίληψη:
in this paper the influence of the shape of the notch on the intensity
of the strain field developed in marble plates subjected to direct
tension was studied both experimentally and numerically. The specimens
were made from Dionysos marble, the material used for the restoration
project of the Parthenon Temple of Athens. The experimental results from
specimens with different notch shape were compared to each other and,
also, with the respective values obtained from a numerical analysis. The
material was modeled as linear elastic either isotropic or transversely
isotropic. The comparison between experimental and numerical results is
satisfactory concerning the specimens with the semi-circular notches.
Deviations are observed for the U-shaped notch, which may be attributed
to the magnitude of the process zone developed, that renders the
elasticity hypothesis, adopted in the numerical analysis, invalid.
