Linear Elasticity - GCMLab/GCMLab-FEM GitHub Wiki

The stress field is related to the elastic strains through the constitutive law,

in which is the 4^th order linear elasticity tensor.

• One-dimensional problems:

  

  in which E is the modulus of elasticity (Young's modulus).

• Two-dimensional problems:

  Plane strain

  

  in which is Poisson's ratio.
