Dear LAMMPS users

I wants to do Fatigue simulations, where we will load and unload the specimen in cyclic manner i.e elongate and compress. Now I wants control the stress here, means in expansion it can go to suppose say 5GPa and similarly it should to go to 5GPa in compression as well. I know there is a command called wiggle where the specimen length oscillates cyclically but here strain is controlled, but I wants stress controlled.
If any body knows, how to control the stress here, or if anybody already did it then please help me in coding. your help is highly acknowledged!!

Yours
Sainath G
