ANSYS qu from new user: help me write a "for" loop please!

Submitted by bumblebee on Sat, 10/18/2008 - 17:31

Hi: I am a new ANSYS user and would really appreciate help writing a "for"-type loop to go with an example found here:

http://www.mece.ualberta.ca/tutorials/ansys/CL/CAT/BirthDeath/Print.html

At the end of the example is the paragraph below. I want to know how to do this! Can anyone modify the code for me? I don't even know where to start. I would be very grateful!

mesh refinement for eigen-properties of a cracked body

Submitted by Arash Zamani on Sat, 10/18/2008 - 09:34

research

fracture mechanics

It is a common technique in modelling cracked bodies with finite element method, to refine the mesh near the crack tip. It is mentioned in text books, mesh refinement is nessecary to increase the acuuracy of the computed stress intensity factor for the crack tip. Is meshrefinement nessecary for computing eigen-properties ( natural frequencies and natural modes ) as well as SIF? or eigen properties are not affected much by the near crack tip field?

An Elastic Plate Problem

Submitted by J. K. Phadikar on Sat, 10/18/2008 - 08:31

It would be very helpful for me if somebody clarifies the following problem: Suppose a beam with simply-supported boundary condition is loaded by uniformly distributed load. One can find out the moment and shear force at any point on the beam by finding forces at the boundaries and then considering equilibrium of some section of the beam.

Fracture energies and strengths of cohesive layer

Submitted by Anonymous (not verified) on Fri, 10/17/2008 - 12:43

Dear Friends,

I am working on damage prediction and cohesive zone modeling. I am looking for fracture energies and strengths for the cohesive layer. We do not have facility for tests. Sometime back I have seen these property values in one paper but now it is missing. Can anyone tell me where I find the material property data for cohesive layer and lamina? Please suggest some literature in this regard.

Regards,

Praveen.

Why rate equations in Nonlinear FE?

Submitted by ramdas chennamsetti on Fri, 10/17/2008 - 12:12

Hi all!

I have a very fundamental question as follwing.

In Nonlinear FE formulations, we use rate equations (virtual work), but, in linear FE we don't use rate equations. Why???

Is it because Nonlinear solution is iterative solution (time may be virtual time).

I request those who have an idea to give some explanations.

Thanks in advance,

Regards,

- Ramdas
