PhD studentship position on "modelling of surface defects transformation in hot rolling of steel"

a PhD student ship is available for UK/EU nationals (ONLY) to develop a Finite Element model of the rolling
operation to predict the behaviour of surface defects on the rolled
material during hot rolling of steels. The effects of geometrical parameters along with the material
properties and the rolling geometry, such as bite angle, on the behaviour of
the surface defects during rolling will be investigated. The
project is partially funded by Tata Steel Europe,

ainsotrpic plasticity in Abaqus

Hello

 

Does anybody know how to input ainsotrpic plasticity in Abaqus?

I have an orthogonal elastoc plastic material and to input elastic properties I use engineering constants but to input orthogonal plasticity (not for all components)  I have no clue.

 

Thnaks in advance,

A Very silly abaqus question... applying a wind load

Dear All,

Sorry to ask such a silly question but I am quite new to Abaqus... I am trying to model a tower exposed to wind. I know how the wind pressure varies according to height, but what I dont know is how to model it in abaqus... Also, if i apply a pressure load, then the load will act normally at all points on the surface, right? But in actuality wind doesnt act that way... Could anyone help me out on this one?

 

Thanks and Regards,

Lekshmi 

Problem Modeling JKR contact using Abaqus

Hello Everyone,

I have been working on solving contact problems relating to fibrillar adhesives over the past 3 yrs of my PhD work. In the past, I used Comsol FEM to model contact interactions by implementing the Dugdale-Barenblatt traction separation law at the contact interface.

Abaqus - Please help!

Hello,

I am a bit confused about a simulation of brittle cracking presented in "ABAQUS EXAMPLE MANUAL" 1.1.5 Collapse of a concrete slab. I was trying to re-simulate the example on my PC and I got really weird results force (RF3) vs. time read in the support point.

Please have a look at attached picture. I download the file mnneice_5.inp from Example 1.1.5 calculated and got totally different resuls. Does it have something to do with setting of my Abaqus software?

Can somebody do the same and check this out?

 Thank you very much for any help!

Submitting number of job at once in Abaqus

To solve several consecutive run automatically by abaqus can get help from the following program:

http://mmd110.persiangig.com/Abaqus/abqscript.bat

First file in the file path. Inp place available.

Then run the file name. Inp file and cpu, and the amount of RAM required by the MB session.

Inp file name (without extension and tandem) and enter them below, separated by a space.

Note: Before entering the first name inp file, insert a space.

Search for a suggestion for Abaqus question

Choose a channel featured in the header of iMechanica: 

Dear all,

       I want to achieve these procedures in abaqus, but I did not know how to do it, could you give me some suggestions?

      In the first step, discretize the structure by the transport mesh and run transport analysis for the structure.

     In the second step, using the results (stored in the user defined field), discretize the structure by the stress mesh(normal stress analysis), and run the stress analysis.

Underlying Material Response for Lüders-Like Instabilities

► The underlying material response of partially unstable materials is measured. ► This is done for Lüders deformed steel and a shape memory alloy. ► They both exhibit an up-down-up response. ► The extracted responses used in numerical models reproduce the structural responses.

Bifurcation Analysis in Abaqus

Hello Everyone,

Im relatively new to Abaqus and I have to carry out a bifurcation analysis of a pipe. Once that is done I need to add the imperfection wavelength and amplitude calculated to the pipe and carry out further simulations.

 

Ive been trying very hard to get a direction as to where to start with it. Can anyone please help me with it? I know that you need to carry out a buckle analysis that will give you a wrinkle pattern on the pipe. This inturn will add up to the bifurcation scheme that you get.

 

Varying Yield Strength through depth in Abaqus

Hi,

I am trying to create a material model in Abaqus such that I have a varying yield strength through the depth (y-coordinate). I want a model which has maximum yield strength at the top surface and gradually goes on decreasing with y-coordinate. Is there a way to do this? Any help/insight would be greatly appreciated. Thank you.

Regards,

Deepak Patil
