[vc_row][vc_column width=”4\/5″][vc_column_text]Simple Shear Testing – approximate cohesion (c) <\/strong><\/p>\n This test is designed to test the shear strength of laminated core. It is particularly suited to sedimentary rocks with a weak bedding plane that is perpendicular to the core. The test involves sitting the core in a saddle and loading centrally so that each end of the core is subject to an equal shear stress. The core almost invariably breaks at one end as one end will be weaker than the other. The value of shear stress at failure is calculated as half the load divided by the cross-sectional area of the core.<\/p>\n
