how can i get the cohesion yield stress in Mohr-coloumb plasticity

Submitted by Gamal on

Hi my friends,

in Mohr-coloumb plasticity model in abaqus program, there is hardening table,this table includes both cohesion yield stress and absolute plastic strain.

the question is this cohesion yield stress is calculated from the stress -strain diagram, or this cohesion is estimated from the shear test, you know when you draw a relationship between shear stress and normal stress you can get both cohesion and friction angle.

the second question is :- how can i see the model while it is running, i am using abaqus 6.6.

thanks alot.

3-Noded Triangle with Drilling Rotations

Submitted by John Craighead on

I'm trying to better understand the 3-noded triangular element with drilling rotations.

I think that the 3-noded triangle with drilling rotations is derived from the 6-noded linear strain triangle by, for mid-side nodes, constraining out-of-plane dof & converting in-plane dof to nodal rotation.

In particular, I'm wondering about the following:

I need help with MIMICS software please

Submitted by nina333 on

Hi all,

 I need some help with MIMICS software please. I have a CT scan images for the whole body and i need to create 3D object for the shoulder model to each part Humerus and Scapula and then perform some measurments then Export it to ABAQUS. Does any one have any idea. Please help.

My email is: ninaall08 [at] gmail.com

 

Thank you with my regards

Elastoplastic deformation of Grey cast iron

Submitted by YangTan on

Hello.all!

Is anyone doing the work on the modeling of  constitutive equation of Grey cast iron in large deformation?

Recently i read  Holm Altonbach's paper "on the Elastoplastic deformation of Grey cast iron" ,  i wonder how to convert the relation (stress-strain) into (stress-hardening parameter). I'm also not sure if the constitutive model can be used in large defomation simulation. 

 thanks in advance!

Forge2008 to Abaqus (.unv to .inp) subroutine Sigini

Submitted by snatsch on

Hello everyone,

I'm working on a linking project between two software: Forge2008 and Abaqus.My goal is to transfert output datas ( nodes,elements, stress tensor) from one software  as input datas for the next one.

In order to realise this task I have to understand the output format .unv of Forge 2008  (Universal I-deas format) and convert this file to .inp ( Abaqus)

And use the subroutine Sigini in Abaqus to put initial conditions.

So to sum up  do you have informations about .unv file (description of elements)

VCCT- Example/Tutoriel for delamination of composite structures required

Submitted by gmaass on

Dear all,

I'm not an expert in using Abaqus. I need an example for modelling delamination with VCCT technique. My model always excited with errors and I dont understand the meaning of them. I posted a blog before, its still that problem. In Abaqus UsersManuel I do not find the right answers. Is it even possible to simulate delamination of a 3d-shell girder with VCCT?

Because VCCT is based on XFEM and I have read somewhere in the Manuel that XFEM is not for 3d-Shell elements. 

 

Thank you

 

Kind regards

Postdoc position at UConn: Mechanical behavior of cellular filaments

Submitted by gelyko on

A postdoctoral position is available at the Mechanical Engineering Department of the University of Connecticut in the area of coarse-grain molecular dynamics simulation of cellular membranes and filaments. Extensive experience in molecular dynamics simulation of soft materials and parallel coding is required. Experience in the use of force fields and LAMMPS is highly desirable.

Hi everybody,I am a senior student in mechanics and I need an example of wave propagation in a thin plate to conduct my project. At now,my main problem is how to model it in Ansys or Abaqus.

Thanks in advance,
