youngs-mod: Young's modulus and elastic constants

In abarbour/stress: Tools for Working with Stresses and Focal-mechanism Inversions

Description

Young's modulus and elastic constants

Usage

shear_to_youngs(mu, nu = 0.25)

shear_to_lambda(mu, nu = 0.25)

bulk_to_youngs(kap, nu = 0.25)

shear_to_bulk(mu, nu = 0.25)

bulk_to_shear(kap, nu = 0.25)

Arguments

mu	numeric; the elastic shear modulus
nu	numeric; the Poisson's ratio
kap	numeric; the elastic bulk modulus

Examples

# Calculate Young's modulus from

# shear modulus
sm <- 30e9
ym.s <- shear_to_youngs(sm)

# bulk modulus
bm <- shear_to_bulk(sm)
ym.b <- bulk_to_youngs(bm)

all.equal(ym.s, ym.b)

smi <- bulk_to_shear(bm)
all.equal(sm, smi)
