Point Load Test of Half-Cylinder Core Using the Numerical Model and Laboratory Tests: Size Suggestion and Correlation with Cylinder Core

Advances in Civil Engineering, 2018
The point load test (PLT) is intended as an index test for rock strength classification or estimations of other strength parameters because it is economical and simple to conduct in the laboratory and in field tests.

Factors influencing economic aspects of operation of tractor machines aggregations

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2004
An appropriate additional load of driving wheels is very important for an efficient use of engine output. This additional load influences significantly the driving momentum and, thus, the pulling efficiency of the tractor. This pulling force is dependent

Effect of Indenter Angle on Bearing Performance of Coal and Accompanying Rocks Under Point Load and Characterization of Mechanical Parameters

Energy Science & Engineering
Coal, mudstone, sandstone, and limestone, which are common in coal mines, were selected as research objects, and 60°, 90°, and 120° indenters were used to conduct point load tests to study the deformation and failure laws of rocks under point loads. This
