Abaqus ALE

Hi every body,

i am trying to use Abaqus/Explicit to simulate a sharp penetration using ALE formulation included in Ver. 6.6, but what ever i do the remeshing module doesn't work. if any body has any information and experience about this kind of simulation i would be pleased to use it as a guid in my analysis.

Best regards

LsDyna - How to use Strain rate and temperature dependant Flow Stress data in tabular form?

Dear friends,

 I am new to this this forum. I salute the founders, administrators and content providers of imechanica for putting up such a useful forum. I work on finite element anaylsis of large deformation and contact problems, in particular metal forming and tribology.

Using LSDYNA to model Fluid Structure Interaction

Choose a channel featured in the header of iMechanica: 

Hi all

I want to use LSDYNA to model a detonation process involving fluid structure interaction. A solid structure is embeded in a viscous fluid media. Due to symmetry of the model, a quarter of the model is analysed. So my question is 

1) How to model the symmetric condition in the Euler element domain? since the Euler meshes is fixed, it seems applying constraint on the nodes in the symmetric plane is meaningless.

2) How to model the infinite boudanry condition in the free surface of the fluid Euler domain?

Thanks

use ABAQUS/CAE in Laser Forming

Hi,

 I am a new user here, and I have two problems to use ABAQUS/CAE,

the first problem, I need some tutorials or helps to simulate a coupled temperature-displacement in ABAQUS/CAE !!

 the second is the major problem, my project is in Laser Forming and I want use ABAQUS/CAE in this domain?

thank you in advance for your assistance

Superplastic Forming (SPF) analysis with Abaqus

Hello world!

I’ve been working with SPF analysis
recently. I followed the Abaqus example to solve my problem. But the result for
my pressure cycle isn’t as expected. It should have increased step by step from
the initial stage as in the real process. If it is possible, I will thank any
suggestions from whom related to this kind of simulation.

OOF

I recently came across this free software - OOF2 on the nist website: http://www.ctcms.nist.gov/oof/oof2/index.html I was basically looking for analyzing the effect of microstructure on the stresses in coatings, and a friend of mine mentioned this software. Since it works only on Unix or Linux (and Mac) I have not been able to install it on my PC...Have a Mac on which i will try it out soon. Will post my experience when I start using it. In the meantime wanted to know what kind of problems others tackle using this software.

Open source codes for microstructural evolution

Modelling and simulation is sometimes said to be the third way of doing science, the first two being theory and experiment; see this essay in Science for example:

What is the status of open source finite element code?

Choose a channel featured in the header of iMechanica: 

FEMs are widely used in education, research, and industries. What is the prospect of having a vibrant community to evolve an open-source finite element code? What are the potential benefits for such a community and code? Has anybody tried?

Presumably whoever active in this effort may find support from government funding agencies and industries.
