How to calculate residual stress in abaqus ? 1

[Lemine]

Hello friends,
How to calculate residual stress in abaqus?
Thanks for helping

 

[FEA way]

Simulate the whole manufacturing process that leads to residual stresses and include additional step where load will be removed (for example by moving the tool away from the part).

Thank you for your response FEA way,
can we calculate residual stress by another method, such variating yield stress?; my structure is subjected to cyclic loading

 

[FEA way]

It depends on the case. What kind of structure is it and what is the source of loading ? Do you use direct cyclic step ?

 

[Lemine]

What is a direct cyclic step?
It's a spherical structure subjected to a cyclic interior pressure.

 

[FEA way]

Abaqus features special analysis step called direct cyclic. It can be used to simulate low-cycle fatigue.

Some kind of pressure vessel, I guess ? If you want to include residual stresses that arose before the cyclic loading step, you can precede this step with another one (general static type) where residual stresses will be generated.
