The ESAFORM 2013 International Conference on Material Forming

Submitted by Robertt Valente on

Dear Colleagues,

Following the last successful events in the past years, the next ESAFORM
Conference on Material Forming (ESAFORM 2013) will represent the 16th
edition of one of the most important and well-established international
research meetings on the material forming field. The conference will be held
at the University of Aveiro, Portugal, from 22 to 24 of April, 2013.

Abaqus: write surface mesh element detail

Submitted by haris33 on

Hi,



i need some help in writing the surface mesh in abaqus. i have a wing model, meshed using hexahedral mesh. now what i want is to write the surface element detail on a file, containing the element number and its neighbouring four nodes. for example



12, 2 3 5 6



here 12 is the element number and 2,3,5 & 6 are the corresponding nodes.



EFG in LS-DYNA for crack simulation

Submitted by Jiang Chen on

Hello, everyone!

I am a graduate student in Hunan Univ, my research field is meshless method. Instead of using codes to calculate, I find EFG has been well developed in ls-dyna, and using software may be more convienient for me.  

But I can only find some introductional information, so I want to find some useful material in iMechnica.com!

THX! 

rotation spring setting

Submitted by hrbeu221 on

Dear all, these days I use combin14 to simulate the boundary conditions. I use two types of springs to simulate support. One is linear displacement spring, the other one is rotational spring. When the spring is on the radial edges, the rotation is about radius direction. When the spring is on the circumferential direction, the rotation is about circumferential direction. So i translate all the nodes to local cylndrial coordinate system. When the spring constants are large enough, the simulation results do not meet well with the clamped boundary conditions.

Fracture mechanics in ABAQUS

Submitted by Dipak Rakshit on

I am new in this forum.I am trying to model Fibre reinfored Polymer

fracture in ABAQUS . But, In website I could not find any example for

that.I have done fracture model for isotropic material such as

Alluminium using Contour Integral.But, for this FRP I am being unable to

model   it.What should be my consideration (different from isotropic)

using this contour integral.I want a tensile matrix cracking or

matrix-fibre interface cracking or fibre cracking. Please help me in

this regard.

Composite Layup ABAQUS

Submitted by s_gupta on

Hi, 

I'm trying to do simulation of a standard shear test of a composite specimen. Hence I'm using the composite layup  to create the section of my specimen. But I'm getting the following error no matter what i do. I have even tried the following tutorial but still I'm getting the same error. The link to the tutorial - https://sites.google.com/site/abaqus2010/tutorial_1/tutorial_1-3c.  

I'm stuck here. Any help would be appreciated. Thanks in advance :)
