How to solve convergence issues due to large Distortion in Abaqus standard?

I am modelling large direct shear test in Abaqus Standard (300 x 300mm box). While shearing for a displacement of 4 mm the model aborts due to convergence issue. I am using Mohr coulomb plasticity...

How can I select the stress within the range? Static creep or repeated load test on asphalt concrete?

The NCHRP rpt 513 says that the range of stress for unconfined test on asphalt concrete (both static and repeated load test) is 69 - 207 kPa and for confined test it is 483 - 933 kPa. The typical...
