Description

AXISTRESSSTRAIN Axisymmetric stress-strain physics mode.

AXISTRESSSTRAIN Define and generate a axisymmetric stress-strain physics mode struct. Used with the ADDPHYS function.

Example

  1) Add default axisymmetric stress-strain physics mode.

  fea.sdim = {'x', 'y'};
  fea.geom.objects = {gobj_circle};
  fea = addphys( fea, @axistressstrain );

  2) Add axisymmetric stress-strain physics mode with named dependent variables.

  fea.sdim = {'x', 'y'};
  fea.geom.objects = {gobj_rectangle};
  fea = addphys( fea, @axistressstrain, {'ur', 'uz'} );

[ PHYS ] = AXISTRESSSTRAIN( SDIM, DVAR, TAG ) Optional arguments when used without addphys are a cell array of space dimension variables SDIM (default {r, z}), dependent variable name DVAR (default {u, w}), mode tag TAG (default css).
