Dear Mechanicians,
 
I would like to draw your attention to the Focus Session **Extreme Mechanics: Elasticity and Deformation** that will  take place at the upcoming March Meeting of the American Physical Society in Dallas, TX (March 21-25, 2011).

Each of the sessions will include an invited talk, followed by a series of contributed talks. This year's invited speakers are:

Abaqus, UMAT, Constitutive law, Powder

Powder

Dear all,

 

I have several questions about how to use existing constitutive law of material to code UMAT in Abaqus. I have carried out experiment for several powder materials, including metal, ceramic, polymer powders. The powder aggregate is compacted in a cylindrical die. After the compaction, relationships between axial stress and axial strain, radial stress and axial strain are obtained. The material under such condition is always treated as elastic plastic material.

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

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

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

3-Noded Triangle
Driling Rotations

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:

creating 3D object

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.

Thank you with my regards

Elastoplastic deformation of Grey cast iron

Elastoplastic deformation
Grey cast iron

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!

Y.T.
