I am Trying to do an Impact test, with Variable pressure on the surface.( M1_ELAS, P14_SOLID)

I am trying to find out either Principal Stresses or Shear Stresses, but the only options regarding the stresses in the ENG_ANIM_ELEM file is either 

  1. Pressure
  2. SIG X,XY,Y,YZ,Z,ZX
  3. VONMISES

Are the SIG X values same as Principal Stress ?

If not can u please tell me how to obtain Either Principal Stresses or Shear stresses From the model..

The Only options I can see in ENG_ANIM_ELEM file are...

DENS,EPSP,ENERGY,DAM1,EPSD,FAIL,HOURG,K,SIG X,TEMP,THIC,TVIS,THIN,VORTX,THKERR,FLAY

 

I am using version 12.0 (Student Edition)

Thanks in advance
