calc_kk_fbmc: Calculate root reinforcement at current strain according to...

In GJMeijer/FBMcw: Generic fibre bundle model for soil reinforcement by plant roots

Description

This function calculates the current root reinforcement, given a strain according to the FBMc model. The results are normalised by the corresponding WWMc model predictions, resulting in a k" coefficient.

Usage

calc_kk_fbmc(epsr0rel, drmin, drmax, betaF, betat, betaphi, dr0 = 1)

Arguments

epsr0rel	tensile strain in reference root, normalised by the tensile strain to peak in this root (numeric array)
drmin, drmax	minumum and maximum root diameter in bundle (numeric array)
betaF	Load sharing coefficient (numeric array)
betat	Power law coefficient for root diameter-root tensile strength fit (numeric array)
betaphi	Power law coefficient for root diameter-root area ratio fit (numeric array)
dr0	Reference diameter (numeric scalar, default 1.0)

Value

numeric array with peak reinforcement preductions 'cr_fbmc'

Examples

calc_kk_fbmc(seq(0,1,l=25), 1, 5, 1, -0.5, -0.2)
