The idea is to link the Lagrange multiplier with the variable uh by imposing that it is equal, in a least squares sense, to the trace on Γ of ... R Codina,J Baiges - 《International Journal for Numerical Methods in Engineering》 被引量: 15发表: 2015年 加载更多来源...
Lastly, even if you're not ready to own Abaqus, you can still take advantage of many of the benefits discussed here on a per-project basis by leveraging ouradvanced FEA services, for which we primarily use Abaqus. Related Articles
THIS MAY BE DUE TO THE UNIT USED FOR THE DISPLACEMENT DIFFERS BY MORE THAN 10 ORDER OF MAGNITUDE THAN THE UNIT USED FOR THE MATERIAL STIFFNESS. IF THIS IS THE CASE, PLEASE USE A DIFFERENT UNIT SYSTEM. OVERCONSTRAINT CHECKS: An overconstraint was detected at one of the Lagrange ...

To introduce a more general method, consider the shallow cylindrical shell below. It is subjected to a single point load at the center, so in this case it would also be tempting to use displacement control. But, as you can see in the graph below, neither the force nor the displacement ...
