Calculate Lamé's first parameter (\(\lambda\))

Calculate Lamé's first parameter (\(\lambda\)) from two of the four other elastic moduli. 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

lame(K, E, G, nu)

Arguments

K

Bulk modulus (Pa).

E

Young's modulus (Pa).

G

Shear modulus (Pa).

nu

Poisson's ratio (Dimensionless).

Value

Returns Lamé's first parameter (\(\lambda\)).
