calc_kku_fbmcw: Calculate sequential mobilisation reduction factor k" for...

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

Description

This function calculates reduction in peak root reinforcement due to sequential mobilisation of roots according to the FBMcw model, compared to the reinforcement predicted by the WWMc model The peak reinforcement is found using the 'optimize' function in base-R

Usage

calc_kku_fbmcw(drmin, drmax, betaF, betat, betaphi, kappa, dr0 = 1)

Arguments

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)
kappa	Weibull shape parameter for the root survival function (numeric array)
dr0	Reference diameter (numeric scalar, default 1.0)

Value

numeric array with reduction coefficients k" (numeric array)

Examples

calc_kku_fbmcw(1, 5, 1, -0.5, -1, 2.5)
