Point load tests and strength measurements for brittle spheres

International Journal of Rock Mechanics and Mining Sciences, 2009
A multiaxial failure criterion for brittle materials is applied to a stress field analysis of a perfectly elastic sphere subjected to diametrically opposite normal forces that are uniformly distributed across small areas on the sphere's surface. Expressions are obtained for an intrinsic strength parameter of the material, as well as its unconfined ...

The point-load strength test for concrete cores

Magazine of Concrete Research, 1980
Synopsis The point-load test, commonly used in geotechnical practice, is evaluated for application in concrete testing. The method uses portable equipment to test concrete cores which require no further preparation after removal from the structure.
