return map algorithm
Dear all,
I am trying to code a UMAT subroutine for perfect plasticity with a Tsai-Wu failure surface. I follow the procedure of the closest point projection in Simo & Hughes, Box 3.5, which is quite straight forward. At least I thought so
The algorithm converges but unfortunately not to the correct point in the (plane-stress) stress space. At first I used an yield surface wich gives a unit sphere in the stress space. It is easy to control the normality of the plastic strain increment and the return-map algorithm is implified to a radial return algorithm.
Smoothed-particle hydrodynamics (SPH) Help
Hi,
I'm a student and now I'm at the beginning of studying the SPD method for my Master thesis. I found a lot of theory on the internet and in books, but what I would need are some solved basic examples (like in the Bathe FE procedures book for example) to see how does it "work". I someone could help me I would be realy gratefull.
About Intergration Points in Eulerian Element (pls help)
Hi!
Good Day.
Please note that I am doing Coupled Eulerian lagrangian(CEL) Analysis using ABAQUS. In this technique, mesh is fixed and material will flow through fixed mesh.
My question is:
1.Are integration points for Eulerian elements are fixed with mesh?
2.If it is fixed, how integration point captured the material behavior (as material is moving through fixed mesh)?
Thanks in advance.
Look forward for your kind reply.
Sincerely-
Sujan.
