Thank you all! :)
@ESPcomposites Yeah I know but I only have to study linear static simulations.(Plastic deformation comes under non-linear, right?) BTW I have other simulation models which includes all manufacturing tolerances. (Clearance between pin and both eyes/tong/clevis AND clearance...
That's pretty neat idea! Thanks.
I performed several more simulations after that(with varying parameters and general contact) here are results if anyone wants to have a look at it and comment. - http://imgur.com/a/xLwK3
This is simulation of knuckle joint with 50KN tensile load on rods. (One end fixed)
Here's how it's assembled, if you don't know what knuckle joint is.

Someone told me it shouldn't deform like this(and the part with two eyes should contract), without...
