Hello ,

 I´m working in my thesis with abaqus only since 4 months, so I´m quite new. I have to simulate the welding of two sheets with electromagnetic pulse process. Under these kind of processes the material is load under high values of velocity and deformations. Taking into account these conditions I have chosen three different flow plasticity models:

-Isotropic plasticity model without strain rate with johnson cook damage ductile criterion.

Dear members:

 I have some basic question:

What is a homogeneous beam? why do we use homogeneous beam ? what are the characteristics of homogeneous beams?

and Where do we use these beams? and what is beam homogenization ?

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?
