A dynamic point-load test for quantifying rock dynamic strength parameters

Review of Scientific Instruments, 2017
The point-load test (PLT) has been widely used in the field and in the laboratory to estimate the strength of rock materials. The PLT is easy and quick to perform and it is suitable for samples with irregular shapes and therefore has found wide applications.

Point load testing for classification of porous effusive rocks

2013
The choice of the ratio K between the uniaxial compression strength (σf) and the size-corrected point load strength (IS,50) for the estimate of σffrom point load tests can have significant consequences on design issues.

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 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 ...

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 ...
