Calculate the Poisson's ratio (\(\nu\))

Calculate the Poisson's ratio (\(\nu\)) from two of the three other elastic moduli to calculate the Lamé's parameter. When more than two values are input, the function will default to using the bulk (K) and Young's (E) moduli. This assumes that the input values represent 3D material properties.

Usage

pois(K = NULL, E = NULL, G = NULL)

Arguments

K

Bulk modulus (K, Pa).

E

Young's modulus (E, Pa).

G

Shear modulus (Pa).

Value

Returns a dimensionless ratio known as Poisson's ratio (\(\nu\)).
