Rolling Ball


 Please refer to the figure given below. I want model this problem using ABAQUS.


A slab (elastic deformable) is resting on two balls (elastic deformable) on a flat surface (rigid). A support acceleration boundary condition is given to the flat surface on which the balls are being supported. I need to model the ball such that it is capable to both roll and slide i.e. I need to assign coefficient of rolling resistance and coefficient of sliding at the contact interface. After the dynamic analysis I will need to measure the acceleration response of the top slab.

 I would appreciate if anyone can provide some tips on modelling this in ABAQUS.

 Thanks in advance.
