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.

3D Elastic Solutions for Laterally Loaded Discs: Generalised Brazilian and Point Load Tests

Rock Mechanics and Rock Engineering, 2013
This paper investigates the application of a double Fourier series technique to the construction of an elastic stress field in a cylindrical bar subject to lateral boundary loads. The lateral loads, including the constant load boundary conditions, are represented by two Fourier series: one on the perimeter of the circular section (r 0 ...

Point of Load for LHC experiments: Testing the behaviour in hostile environment

2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2014
Devices used in future experiments at LHC will be called to work in a very hostile environment. Power supply is a key aspect in this scenario, and new converters will be re-designed in order to meet the future requirements. Moreover, also Point of Load (PoL) converters, as circuits able to adapt the voltage level for each board, device and situation ...

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.

POINT LOAD TESTING OF FLEXURAL BEHAVIOR OF SEGMENTED TUNNEL LINING

Malaysian Journal of Civil Engineering, 2018
In tunnel, design of precast tunnel lining are not merely about the strength, but how much its allow to move to account the deflection comes from movement of surrounding soil and load. Thus, the design of tunnel lining is not straight forward. Understanding the flexural behavior of segmented lining is a bonus to optimize design lining in cost effective
