Translations:FEM EquationDeformation/12/en

The deformation equation provides these special settings:
 * : If the principal angles should be calculated.
 * : If all stresses should be calculated.
 * : If strains will be calculated. This will also calculate the stresses, even if or  is false.
 * : If stresses should be calculated. Compared to the Tresca yield criterion and the principal stress will not be calculated.
 * : See the Elmer manual for more info.
 * : See the Elmer manual for more info.
 * : Uses the neo-Hookean material model.
 * : The variable for the elasticity equation. Change there the 3 to 2 if you have a 2D geometry. For the special case that you have and  set to true, the variable number must be geometry dimensions + 1, so for 3D geometry the 3 must be changed to 4.
