Sažetak
The Vickers microhardness of three different sea mollusc shell structures has been determined as a function of the indentation load. The following shells from the Adriatic Sea have been investigated: abalone, (Haliotis tuberculata), smooth clam (Callista chione), and warty venus (Venus verrucosa). The results show that the measured microhardness depends on the load for all of the investigated seashell structures, which indicates the influence of the indentation size effect (ISE). The load dependence of microhardness is analyzed by using the known Meyer’s Law, the proportional specimen resistance model (PSR), and the modified proportional specimen resistance model. The best correlation between measured values and used models is achieved by using the modified PSR model.
