This paper presents the theory for the Lagrange co-rotational (CR) formulation of finite elements in the geometrically nonlinear analysis of 3D structures. In this paper, strains are assumed to be small while the magnitude of rotations from the reference configuration is not restricted. A new best fit rotator and consistent spin filter is derived.

Hello
I am working on the simulation of ring rolling. I have written the subroutine for the plasticity part in the subroutine VUHARD and have set the PLASTIC part in material definition to USER.
I dont have HARDENING PROPERTIES so i have set it BLANK. i have set the path of the subroutine in the job defintion part too. But abaqus crashes whenever i try to do DATA CHECK
It says ABAQUS KERNEL EXITED WITH AN ERROR.I dont know why this problem arises?. I am stuck.
Hi All Currently I am running FE modelling using linear elastic fracture mechanics approach to estimate crack growth propagation in a web plate of box girder in an existing bridge deck. The FE model includes 3D solid element. The crack growth direction is expected to follow in a plan perpendicular to the maximum principal stress. As I know there are many methods can be used to estimate the direction of crack during propagation. My question is about the maximum tangential stress criterion method.
Hi,
I am looking for a good citation (or perhaps a detailed explaination) on the difference between material co-ordinate and eulerian co-ordinate system.Please treat me a beginner in the field of continuum mechanics.Thanks for your help in advance.

I am co-organizing a mini-symposium on Cohesive Zone Models –
Fundamentals and Multiscale Applications (MS-139) in
the World Congress on Computational Mechanics (WCCM 2012) with Dr.
Glaucio H. Paulino at the University of Illinois at
Urbana-Champaign. We welcome papers that present theory and
applications of cohesive zone models at any length and time scales,
from atomistic and molecular to microstructural and phenomenological
models. Please, see the attached PDF for more detail of the
mini-symposium.
Dear friends
The obtained results from my model show that the ultimate load is higher
than the expected one. after checking the results, I found out that the
tensile stress of concrete is much higher than input value for the
tensile yield stress. "concrete damaged plasticity model" is applied.
your help is highly appreciated.
