How can I study residual streeses impact in the fatigue life of 2 specimens .

2 cylinder same work conditions, material, dimensions but one normal and other with beneficial compressive residual stresses ,

residual stresses gained by plastic loading before working process

How can i take the residual stresses results and put like prestressed in the work process

2 stages we cannot mix them but results related

Hi @mohamadmourad ,

If you have stress data along with the location of stress at particular nodes then you can use the External Data module to apply the stress as the initial condition.

Sorry- forgot to add the link for External Data use: https://forum.ansys.com/discussion/23559/how-can-i-study-residual-streeses-impact-in-the-fatigue-life-of-2-specimens#latest
