Any suggestions on what Winkler (or other method,) stiffness to use when running FEA of ~3/4"x3/4" metal stakes pounded 12~18" into the ground? Primarily worried about lateral load but also interested in pullout/push in resistance. I'm an ME and can handle the stake bending portion of the analysis and have been using a 'spring' in FEA (COSMOS,) to restrain the stake... just not sure what stiffness values I should be using.


Thanks.
