von Mises or Equivalent stress for Beam Elements
Are there analytical expressions for computing von Mises or equivalent stress at any point for Beam elements similar to the ones in continuum elements? I would like to design a structure with beam elements and ensure that the equivalent stress is within bounds (yield stress etc) for the structure to be safe.
Converged, but to the right solution??
Hello eveybody,
I am confused in using numerical schemes: What can convergence of a numerical scheme tell us and what not??? lets assume that a numerical scheme does converge to "A result" or "A number", but how could we be sure that the scheme has actually converged to the "RIGHT solution" and not a WRONG one??
Any input is appreciated!

Symposium at 2015 Mach Conference
Dear Colleagues:
We are organizing a symposium titled "To Yield or Not to Yield: Multiscale Perspectives in Plasticity and Failure of Materials" at the 2015 Mach conference, which will be held in Annapolis, MD, USA during April 8-10, 2015. We cordially invite you to participate in the 2015 Mach Conference by giving a talk in our symposium.
Rigid-plastic flow
The attached notes are written for a course on plasticity. When I update the notes, I will post a link on my twitter account: https://twitter.com/zhigangsuo.
PhD Position at the University of North Carolina at Charlotte
I am seeking Ph.D. students to work on developing and using multiscale methods for modeling nanocomposites and nanomaterials. Candidates should have a BS or MS degree in mechanical engineering, material science, civil engineering or other related areas. Candidates with computational solid mechanics experience at the continuum or molecular level are highly preferred.

Green–Lagrange strain for Shell: transformation from curvilinear coordinate to local Cartesian coordinate
Hello all:
I am confused about how to transform Green–Lagrange strain defined using curvilinear coordinate to local Cartesian coordinate.
