I need this paper for reference. But I cannot find the full text. Could anyone, who has a copy of it, send a copy to me? Thanks so much.

does anybody know how to use the material model no:185 in ls dyna for modelling cohesive zone elements for analyzing the crack propagation in a ct specimen made of steel?

Hi my friends,

I want to export both the stresses and the co-ordinates (x,y,z) at the

integration points using Abaqus CAE. I know how to get the stresses at the nodes

(unique nodal ) by using Visulaization module then report then unique nodal. But

when i try to report the stresses at the integration points, i did not find the

co-ordinates at the integration points as one of the output. I find only the

unique nodal.



Thanks alot,

I created a 3D model in Ansys, and when I wanted to mesh, I realised that the model was created in the wrong plane:  the area I wanted to mesh was in the x-z plane, while the plane82 element I needed to use needs to be in the x-y plane.

 Is there a way I can rotate my entire model instead of starting from the beginning?

In addition, how can I create a cylinder with the circle in the x-z plane and its depth in the y direction.  Creating circles and cylinder only gives the option to create the circle in the x-y plane.

Thanks

Hi,

I am solving an implicit non-linear problem in LS-DYNA. I was not able to achieve convergence. I changed the default displacement andenergy norm (which are 0.001 and 0.01 respectively) to 0.009 and 0.05respectively, the solution converged. My question is, is it advisable to changethe default norms to achieve convergence?

Madam,

I want to make a simple composite structures of concrete embedded steel in abaqus. (If I am wrong kindly say) I have creted a "dependent" instances in the assemble module after doing the mesh. Then I have made the interaction with the step-1 and made a "surface to surface contect (standard)" having the master (concrete) and slave (steel) with contact (friction) property.

1. i am doing M.E in tamil nadu....am doing final year project in composites material...i.e., delamination analysis of composite material in glass fiber with epoxy.....i do the analysis in ANSYS 12...i saw in ANSYS there is APDL program as same as my project...i.e., VM 248.......i need step by step instruction of APDL program.....pls hepl me as soon as possible..........

As we known,  boundary element method (BEM)  is a quite popular numerical  method.  But there are some problems. My research fields are computational mechanics and BEM (including fast BEM).  We can discuss these fields in this blogs. I am waiting for you! Thanks
