Hertzian contact - sphere and half-space

Hello,

 

I would like to calculate a contact between a sphere and flat solid block, pressed together under certain load. I am interested in the contact stress and precise contact area (I would like to compare the results with the analytical solution of Hertzian contact theory).

Is it feasible to get the desired results with a non-linear quasi static analysis in Optistruct or shall I do it with Radioss? Additionally, what is the best way to obtain the final nodes in contact or even to fix them together and perform an additional analysis?

 

Thank you for you help,

Matej

    Hi Matej,

     

    Yes, you can go ahead with Quasi static with large displacements. But I would recommend using NLGEOM or using RADIOSS as the strains may be higher than 6%
