  • The effects of the static model and strain rate model used for the L80 HSM-2 premium connection on the calculation of make-up torque, stress strain and sealing contact pressure are analyzed by use of ABAQUS software and the analysis is compared with the experimental cases.The results show that the yield torque is seriously low, the yield torque of the premium connection appears prematurely and the equivalent plastic strain is higher when calculating by the static model, while the yield torque conforms to the actual cases with the material strength increased when calculating by the strain rate model.The calculation results of the sealing performance are basically consistent when calculating either by the static model or by the strain rate model.
