Hey!
I need to model a sphere of 3-30 micrometers in diameter made of polymer with addition of an nickel coating layer of 50 nm, followed by a layer of gold with thickness 30nm. The composite sphere is to be static in contact over a flat metal plate. Then, I need to apply a consentrated pressure load over the top of that sphere so that contact stress is developed between the sphere and flat plate. The plate should be constrained from movement in all directions and the sphere should be constrained from movement in all directions except along y-axis(U2) since the load has to be applied over the sphere and it should move along y-axis to generate contact stress over the sphere and plate. The sphere is deformable. And I need to know how to model and mesh it. Can someone tell me how to model this problem in Abaqus?
Thanks guys!
