ansys

can anybody tell me how to model composite plate in ansys?? And how to solve it? Specify me what type of element should be used.

Corotational formulation for 3D solids

lagrangian formulation

Please have look

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

Plasticity

User subroutines in ABAQUS

VUHARD

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?

opinion

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.

material co-ordinate systems

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.
