Hi

I would like to know where can I find the articles mentioned in Abaqus documentation:

>>> Krieg,  R. D., and D. B. Krieg, “Accuracies of Numerical Solution Methods for the Elastic-Perfectly Plastic Model,” ASME Journal of Pressure Vessel Technology, vol. 99, no.4, pp. 510–

515, 1977.

>>> Schreyer,  H. L., R. F. Kulak, and J. M. Kramer, “Accurate Numerical Solutions for Elastic-Plastic Models,” ASME Journal of Pressure Vessel Technology, vol. 101, no.3, pp. 226–234, 1979.
