For Geotechnics Abaqus Users!

Submitted by ziyad on Thu, 06/25/2009 - 19:23

Hello colleagues,

Iam trying to model load test on board pile. I have already a model which is working but not as I need. I think the interaction between pile and soil is not correctly defined. Has someone an experience with this issue.? How I should define the interaction between soil and pile?

Attached .inp file.

poroelasticity

Does anyone have experience using poroelasticity model? I dont underestand the abaqus model -the logarithmic bulk modulus and.., where are these coming from?Is anyone knows a reference book to link those?

dynamic crack propagation

Submitted by llguang on Thu, 06/25/2009 - 14:04

Hello everyone, I am useing the CZM method researching the dynamic crack propation problem in composites,so I must have the UEL OR VUEL of cohesive zone elements in ABAQUS or other FEM software,at this moment, i have a UEL of ABAQUS,so i have a question ,if i want to simulate the dynamic crack problem, can i use the UEL? Or must write my VUEL?

Everyone answer is welcome

If some people have the same researching plan ,we can communicate each other!

For metals, when will the elastic modulus be changed?

research

I have a question, for the same metal material, when will the elastic modulus will be changed? in another words, in what kind of processing or machine condition will the elastic modulus be changed? for example, to machine elements(gear, bearing ...), when the part surface is case hardened,will the elastic modulus be changed? if not, how can the difference of hardness between case hardened surface and without hardened substrate be reflected in FEM analysis? how can the case hardened surface parameters affect the contact stress when two part are brought to contact?

Pullout force in Abaqus( NFORC3,RF3???)

To be precise this is what i am doing

I have 2 cylinders( which
would later be replaced by stent and hollow tube resembling artery) one
made of Nitinol and other made of Hyperelastic Material PDMS( material
properties are inputted)

The Outer diameter of the Inner cylinder is
7.5mm while in the Inner Diameter of the Outer cylinder is 7mm. The
Outer cylinder is Hyperelastic, Inner is Nitinol

These are my steps

Step1: Compression of Nitinol cylinder

Step2:

Modeling of Droplet spreading

Submitted by hfawad on Wed, 06/24/2009 - 04:50

dear all

i am trying to model droplet impact and spreading and i am thinking of using comm code CFX for this purpose

Can CFX handle this sort of problem? or if some one can help me out with an alternate

thanks

heat transfer and stress analyses

Hi,

Are there researchers working on specific areas in offshore structures? Or is anyone covering the material behaviour of structures at elevated temperatures? I am indeed challenged to read about excitng contributions from different scholars expecially in structural mechanics. I realise I have just begun a race in research. You could help me gain the proper direction in research.

I shall be glad to get any response.
