For defining cohesive behavior in ABAQUS we can either use ABAQUS's 'use default contact enforcement method' (Fig attached) or choose to specify the stiffness coefficients ourselves. From the ABAQUS manual I can only find mention of the point that the default traction-separation behavior is uncoupled; but there's no mention of the default stiffness values used by ABAQUS.
Can anyone suggest me where I can find the default stiffness values used by ABAQUS?
