## Modeling Concrete!

Dear guys!

Is there anyone who made a dynamic model of concrete in Abaqus/Explicit?

I need a *.py file of concrete modeling!

Hi all,

I want to generate moving cyclic load to analyse bridge. I have written dload subroutine. But when I am trying to submit the job, its only showing that "JOB has been submitted for analysis". But its not doing anything. Please help on this issue.

Thanks,

Nondon

## Request Elasticity Lecture Notes

Choose a channel featured in the header of iMechanica:

Hi all,

Do you have some lecture notes in Elasticity course? Especially about plane stress/strain, airy stress function, variational and energy method?
Because I really want to improve myself in this.
And if I have a potential energy equation by variational principle, how can I obtain the displacement equation?

Thank you very much.

Best,
Ray

I have just started working on ABAQUS (6.6.1) and have practised simple tutorials.I need to work on the plastic analysis of tubular structures..If any one of you have got any tutorial on tubular structures..please send me..Expecting a positive response.....

Thank you,

## System of unit in abaqus

Dear guys!
I've a qustion about system of units in abaqus!
I thought that the system of units in a model must be the same but in abaqus example "stiffened plate under the blast load" in define the material the density defined in "kg/m^3" but other properties defined in "Pa"!
Is that true? if yes why?

## parabolic forth order PDE

I have advance vibration this term and one of our research homework is to find all solutions that have been presented for parabolic forth order PDE. I am looking for some reference for it. Is there anybody know about it?

## resonance (natural) frequency of a cantilever beam

Choose a channel featured in the header of iMechanica:
Free Tags:

resonance (natural) frequency of a cantilever beam is given by

f=[kn/2pi][sqrt(EI/wL^4)] where, kn=3.52 for mode 1, E is Young's modulus, I is moment of Inertia, w is beam width, L is beam length. (this is from Formulas for Stress and Strain, 5th edition by Raymond J. Roark and Warren C. Young).

I would like to derive this formula. Can any one suugest me any book or any link?

Hi

Is there anyboby to help me. Actually I am facing some problem during the use of SIESTA (Spanish Initiative for Electronic Simulations with Thousands of Atoms) package. The problem is that How to generate the Pseudopotential file. And the use of Vibra utility. During the use of Vibra package i cant able to run it properly.

## plane stress problem in abaqus

hi all!

i am a new user of abaqus. i am trying a simple problem of a plate. the plate is made of composite material (orthotropic). i give all the properties correctly. but after submitting the job i get an error that 'laminate type- can be used with plane stress elemnts only'. how could i rectify this? can anyone tell me how to model a plane stress problem in abaqus? what is the significance of plane stress/strain thickness ratio.
