Because of the very small area involved in what initially approximates a point or line contact, the stresses obtained from the equations in Table 11-1 are high even for light loads. However, since the stress is highly localized and triaxial, the stress intensity may be very high (above the yield point) without producing apparent damage.

2006-3-19 · rock. As shown in Figure 4a, a line load creates a uniform tensile stress across the loaded diameter accompanied with a vertical compressive stress. Failure is assumed to start at the center under a state of stress where P is the applied load, D is the core diameter and t the core thickness. Equation (4) can only be used if the rock is isotropic.
By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.
