calc_cru_wwmc: Calculate peak root reinforcement according to WWMc model

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

Description

This function calculates the peak root reinforcement according to the Wu/Waldron model, assuming a continuous, power-law distribution of root area ratio across a range of root diameters

Usage

calc_cru_wwmc(drmin, drmax, tru0, betat, phir0, betaphi, k = 1.2, dr0 = 1)

Arguments

drmin, drmax	minumum and maximum root diameter in bundle (numeric array)
tru0	Tensile strength of root with reference diameter (numeric array)
betat	Power law coefficient for root diameter-root tensile strength fit (numeric array)
phir0	Root area ratio of root with reference diameter (numeric array)
betaphi	Power law coefficient for root diameter-root area ratio fit (numeric array)
k	Wu/Waldron factor accounting for root orientations at failure (numeric scalar, default 1.2)
dr0	Reference diameter (numeric scalar, default 1.0)

Value

numeric array with peak reinforcement preductions 'cru_wwmc'

Examples

calc_cru_wwmc(1, 5, 10, -0.5, 0.01, -0.2)
