Applying load on a Compact Tension specimen in Abaqus

Hi there,

I have been trying to model fracture toughness test in abaqus but unfortunately I am faced with difficulties of how to apply the tensile loading on the compact tension model's pin holes. Most papers I have come across show only pressure being applied on the flat upper most edge of the test specimen instead of the pin holes. Please could there be someone out there who could show me how to apply this tensile loading right on the holes?

Thanks in advance.
