摘要：

An accurate numerical algorithm for the integration of constitutive equations under both large deformations and/or large rotations is presented. The algorithm is based on the choice of the unrotated configuration as the frame of reference for all constitutive equations. The algorithm does not entail excessive computational time or memory expense. The accuracy of the method is demonstrated by several numerical examples.
