Compute plane stress tensor from plane strain tensor

Description

Compute plane stress tensor from plane strain tensor

Usage

stresses(
  E11,
  E22,
  E12,
  G = 3e+10,
  nu = 0.25,
  extension.positive = TRUE,
  as.mat = TRUE
)

principal_stresses(S)

Arguments

E11, E22, E12	numeric; strain components in 1-2 coordinate system
G	numeric; elastic shear modulus; 30 GPa is a reasonable value for deep crustal rock
nu	numeric; drained Poissons ratio; 1/4 is a reasonable value for a Poissonian solid
extension.positive	logical; positive extensions are extensional
as.mat	logical; should the result be returned as a matrix?
S	symmetric stress tensor
