How to define a displacement rate as a pressure uniform load?

Dear All,

I would like to simulte a 2-d tension test which has been conducted using a displacement rate 1mm/min till failure. Can some one explain how to define this displacement rate using Abaqus 6.7? Also, I would ask another question, can this displacement rate be considered as a vilocity? and can be modeled as a velocity field?
