  Can ANSYS workbench produces creep strain energy density as simulation output? If yes, may I know how to do so?
  
  Thank you

  Not directly. If the loading is constant then perhaps creep strain energy is equal to the change in elastic strain energy (ETABLE,,SENE). Element volume is available with ETABLE,,VOLU so, in this example, creep strain energy density could be computed with commands like the ones below:
  /post1
  set,1,last
  etable,sene,sene
  etable,volu,volu
  ssum
  *get,sene_ls1,ssum,,ITEM,sene
  *get,volume,ssum,,ITEM,volu
  set,2,last
  etable,refl
  ssum
  *get,sene_ls2,ssum,,ITEM,sene
  creep_strain_energy=sene_ls1-sene_ls2
  creep_strain_energy_density=creep_strain_energy/volume
