Anisotropy, Point and Line LoadsAbstract:
To measure the tensile strength, the load applied can be either tensile or compressive. The application of compressive load in order to induce tensile stresses can be either through point load (diametral loading) or line load. In this paper, for twelve variants of basalt and twelve variants of gneiss, an attempt has been made to correlate the two loads, i.e., point load and line load, to induce tensile failure. For each of the variants, the correlation between the point load and the line load data is discussed on the basis of recommended parameters only; in other words, the inherent variability of a given variant is not in focus here. The reported work also draws from previous researches and codes of practice. In case of Basalts, the ratios are ranging from 0.65 to 0.78. While, due to anisotropy in Gneisses, the ratio is ranging from 0.79 to 2.28, but, it is also observed that the ratio is decreasing to 0.80 as the value of anisotropy index is approaching unity. However, it can easily be inferred from the study that the ratio is rock type specific.
