John W. Hutchinson is awarded the Ludwig-Prandtl-Ring
Professor John W. Hutchinson, of Harvard University, will receive the 2012 Ludwig-Prandtl-Ring. The award is the highest honor bestowed by the Deutsche Gesellschaft für Luft- und Raumfahrt, the German Society for Aeronautics and Astronautics. Ludwig Prandtl was a great pioneer of modern Aerodynamics. The Ludwig-Prandtl-Ring is awarded annually to the maximum of one individual for outstanding contributions to Aeronautics and Astronautics.

Corotational formulation for 3D solids
Please have look
http://arxiv.org/abs/1110.5321
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.

ABAQUS VUHARD subroutine problem
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.
How to estimate crack growth propagation using the maximum tangential stress criterion method?
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.
continuum mechanics
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.
