In Part 5 of my series on return mapping for plane stress plasticity, I claim that the obsession with backward Euler is not justified if accuracy is important. See http://www.parresianz.com/mechanics/plasticity/algorithm/plane-stress-drucker-prager-return-part-5/.
Let me know if you disagree and why.

Parts 3 and 4 of the series on plane stress Drucker-Prager plasticity are now online. More to come soon.
Check out

The attached results address the extent to which the presence of a nanograined, dynamically recrystallized phase may soften a material (in that case Ti6Al4V), causing ultimately failure by shear localization.
Comments welcome.

I have been told that it is no longer needed to search for papers on regular libraries and libraries' services, as there is this web site which contains much more than even the best "legal" library www.sci-hub.cc
