How can I retrieve maximum membrane, bending and total stress from a linearized stress plot in Mechanical APDL?

      Once the linearized stresses are plotted through PLSECT command :

      – Create an array to store values :
      *dim,test_smb,array,3,3

      – Calculate the linearized stresses through PRSECT :
      prsect

      – Use *GET function to store inside, center, and outside values for membrane, bending, and total stress :
      *get,test_smb(1,1),section,membrane,inside,s,eqv
      *get,test_smb(2,1),section,membrane,center,s,eqv
      *get,test_smb(3,1),section,membrane,outside,s,eqv
      *get,test_smb(1,2),section,bending,inside,s,eqv
      *get,test_smb(2,2),section,bending,center,s,eqv
      *get,test_smb(3,2),section,bending,outside,s,eqv
      *get,test_smb(1,3),section,total,inside,s,eqv
      *get,test_smb(2,3),section,total,center,s,eqv
      *get,test_smb(3,3),section,total,outside,s,eqv

      – Use *VSCFUN to get maximum value for membrane, bending, and total stress :
      *vscfun,memb_max,max,test_smb(1,1)
      *vscfun,bend_max,max,test_smb(1,2)
      *vscfun,bend_max,max,test_smb(1,3)
