An implicit numerical algorithm for the integration of the primary/secondary creep constitutive law at the material point level is derived. For the presented constitutive model, the experimentally obtained material parameters for the medium density polyethylene (MDPE) are taken from literature. The derived algorithm in conjunction with the Jacobian matrix is implemented in the finite element (FE) code ABAQUS by using the user subroutine CREEP. The accuracy of the proposed algorithm is demonstrated.
