UCS: Uniaxial Compressive Strength (UCS)

In maxgav13/GMisc: Miscellaneous Functions for Geology (and its areas)

Uniaxial Compressive Strength (UCS)

Description

Calculates different possible values of UCS based on point load test measurements. It performs several regressions (Gaussian and robust), and also calculates corrected value based on the point load index.

Usage

UCS(W, D, P, digits = 2)

Arguments

W	A vector of sample widths, in mm
D	A vector of sample diameters, in mm
P	A vector of loads at failure for each sample, in kN
digits	Number of significant digits to display (Default is 2)

Value

A comparison table and graph

Examples

W = c(70.0,95.0,80.0,90.0,98.0,110.0,100.0,100.0,110.0)
D = c(40,55,60,50,25,60,40,70,50)
P = c(4.3,3.4,4.5,3.1,5.0,6.4,2.6,11,4.1)
UCS(W = W, D = D, P = P)
