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.

Strength determination of high-power LED die using point-load and line-load tests

Microelectronics Reliability, 2012
Abstract The strength of high-power light emitting diode (LED) dies, cut from wafers with a laser, has to be determined for the need of design and quality control in order to assure the good reliability of packages in manufacturing and service. The objective of this study is to determine the strength of high-power LED die with a size of 1 × 1 × 0.1 ...

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 ...

A New Procedure for Determination of Point Load Strength in Site Investigation

Geological Society, London, Engineering Geology Special Publications, 1986
Abstract As a result of developments over the last twenty years, the point load test has become a cheap and practical method for field and laboratory determination of rock strength. Since point load strength is size dependent, the test results are generally corrected to a standard thickness of 50 mm by using empirical ...

The influence of foliation on point load strength anisotropy of foliated rocks

Engineering Geology, 1990
Abstract The engineering behaviour of rocks depends upon whether the fabric is isotropic or anisotropic, which is a reflection of its genetic environment. Even though anisotropy in fabric can occur in nearly all natural environments, metamorphic terrains usually offer the main source of anisotropic fabric elements.
