hertzian contact stresses, Stratic structural, equivalent stresses
I am simulating hertyian contact stresses and i have the boundarz conditions as
- Force 200N load ( red region in the image) on the outer ring
- other ends of the shaft are fixed
I have used share topology and the rolling eleimint is getting twisted and the simulation isnt giving expected results.
If i dont use share topology the elements are not contacting and moving away each other.
I have used a frictional contact between outer ring and rolling elemnt and outer ring and surface of the shaft.
i have usef augmented lagrange method formulation and stiffnes factor from 0.1 to 1.
I have given the interferance treatment to adjust to touch .
please suggest me what went wrong and any other boundary condition to stop the twisting of rolling element.
