Influence of nonlinearity and double elasticity on flexure of rock beams — II. Characterization of Dionysos marble

Acoustic Emission Analysis of Cement Mortar Specimens During Three Point Bending Tests

“…This is clearly seen in Figure 5 where the load induced is plotted against the deflection of the central section for a typical specimen. Similar behaviour is observed in most rock-like materials, for example Dionysos marble (Exadaktylos et al, 2001), when loaded in bending.…”

Correlation between the electric and acoustic signals emitted during compression of brittle materials

“…The as above experimental protocols revealed also that Dionysos marble is slightly non-linear (both in the tension and in the compression regime) and slightly bimodular, i.e. the elastic modulus in compression is about 15% higher than the respective one in tension [24,25]. Three marble specimens were used in the present study of prismatic shape with dimensions 40 mm x 40 mm x 100 mm.…”

“…it is characterized by three different anisotropy directions. However, it can be approximately considered as a transversely isotropic material described adequately with the aid of five elastic constants as it was definitely concluded by detailed experimental protocols including direct tension and compression tests as well as three-point bending and Brazilian Disc tests [22][23][24][25][26][27][28][29]. The as above experimental protocols revealed also that Dionysos marble is slightly non-linear (both in the tension and in the compression regime) and slightly bimodular, i.e.…”

A Combined Experimental and Numerical Study of the Pull-Out Mechanism of Threaded Titanium Bars Embedded in Marble Blocks

“…7(a), where the variation of the load is plotted versus the bar's axial strain. The differences observed, concerning the maximum load attained are significant and could be well attributed to uncontrollable parameters related to the inhomogeneity and anisotropy of Dionysos marble [8,9], which dictate marble's response. On the contrary, the differences observed for the overall stiffness of the system (namely the slope of the load -axial strain curve) are rather negligible.…”
