HOW TO FIND K-DOMINANT REGION

Submitted by ravitejk4u on Tue, 01/29/2008 - 13:01

hii all..

i am working on fracture mechanics. i had modeled a 4 pt bend specimen having single notch crack(in ABAQUS). i am trying to find the range of K-dominant region at the crack tip.i had modelled radial mesh at the crack tip and using 20 noded reduced integration elements. To analyze the K-dominat region, primarily i had compared the theoritical stress plots and computational stress plots. stress plots means Sxx Syy Sxy values plotted againt the angle(angle measured from uncracked segment) at particular radius.

primary unknown of FEM formulation

In beam FEM problem generally the nodal displacement (v) and slope (θ) are taken as primary unknowns to determine the element shape function. What will be the obstackle/s if, instead of considering the slope, the nutral axis curvature (κ) is considered as primary unknown along with the displacement?

Software for meshless....

meshless software

I would like to know which software is people using for meshfree simulation. Is there any more or less "standard" one that people tend to use? I'm interested in knowing about any one for any kind of problem.

Structural Analysis of 3D Panel buildings

Submitted by odlanierzenitram on Sat, 01/26/2008 - 20:28

I am in urgent need to present structural analysis for construction permits on this simple, small house I designed.

Can anyone present some step-by-step produre to do the analysis of a simple room with these 3D Panels? This way I can proceed to do the entire house.

Or is there any software that can help us in this?

Please e-mail replies to odlanierzenitram at yahoo dot com

Modeling and Simulation

computational

I am looking for two postdocs in the analytical and computational modeling areas. One position will focus on the theoretical and computational modeling of microstructure-modulated failure processes, with an emphasis on nanocrystalline materials. The other will focus on hypervelocity impact fragmentation problems, including planetary scale impact and fragmentation. The latter position is available immediately, and the former is available as of June 1, 2008.
