(2) groundplate shows -1
(1) washer shows 1
Why? If i understand correct -1 is tension only and 1 compression only.
Or does it have to do with the coordinate system?
Anyway as booth are currently set just as compression only they should have the same direction with -1 or 1?
it depends on the face of solid element, bottom surface meaning compression only and top surface of washer areas doing similar (activate) when subjected to uplift force. There’s no required any input to modify in this case, some comment about transversal spring ;look may not appropriate since it’s position in wall perimeter holes area, not in washer. Another disadvantages of these model approaches are strictly to linear spring stiffness by gap element.
when the baseplate of my model is thin, both of the surface support will be active due to prying action. Sum of support reaction also greater than force applied, cause of kickback.
