Analytic Solutions for Diametral Point Load Strength Tests

Journal of Engineering Mechanics, 1998
This paper investigates the tensile stress distribution within a solid circular cylinder of diameter \iD and length 2\iL subjected to double diametral indentors or diametral point load strength test (PLST). The contact problem between the indentors and the cylinder is solved analytically, and exact solution for stress distribution is obtained through ...

The point load test for weak rock in dredging applications

International Journal of Rock Mechanics and Mining Sciences, 1997
Abstract The point load test is shown useful for weak/saturated rocks which are commonly encountered in mechanical dredging operation. To support the dredging use of the point load test, orginally intended to obtain a field strenth index for hard rock materials, a comparative, testing program was initiated, which included more than four hundred rock ...

The Point Load Test in the Persian Gulf Carbonate Rocks

2009
The Point Load test is an index test used to provide an economical and quick estimate of the Uniaxial Compressive Strength (UCS) especially for highly fractured rock cores that with geometry not suitable for UCS testing. This is usually done using an empirical conversion factor (K) between the Point Load Index of 50-mm diameter rock cores (Is50) and ...

Some new aspects on the diametral point load testing

2018
A new closed-form equation is presented to measure the tensile strength of rock based on point load strength index. The validity of the proposed equation is further examined experimentally through a set of diametral point load testing of monzonites and two different types of granite having various slenderness (length to diameter) ratio.
