Hello,
My problem is quite simple. To the effect of I am not getting the right answers and I am blind to any problems that ABAQUS may be having.
Working with a 3.175mm wide block with a 90degree wedge and a fillet of 1e-30 fillet. Indenting with a load of 11490N into a block with Young's Modulus 205GPa and Poisson's ratio 0.29 and a perfectly plastic property with Yield Strength at 420MPa.
Boundary conditions are the bottom of the block is encastre (so the wedge doesn't simply push it down), the sides are XSYMM and the wedge has conditions of only moving the the Y-direction.
The wedge is the master surface with the top of the block surface being the slave and the interaction properties are tangential with 0.2 friction coeff and normal with hard contact.
The results I am comparing are the indentation vs reaction force, both in the Y-direction.
This experiment has been done in a lab and found to have an indentation depth of around 0.05mm-0.5mm. However I am only getting an indentation depth of around 0.0006mm. It is not even reaching plastic deformation...
Is there something I have missed or neglected?
Any help would be appreciated,
Thank You
