Abstract: In this paper, the consistent tangent modulus method is compared with the radial return mapping algorithm and it is found that the former is not more numerical efficient than the latter, not as some paper reported. Two numerical examples are given.
Keywords: consistent tangent modulus, radial return mapp ing, iterative step, load step.
