Shell vs. brick elements in buckling analysis
Dear All:
I have a structural problem which deals with "Buckling" analysis of a boom with a rectangular cross-sectional area
and 0.25 in. thickness.
Can I use brick element (8 nodes) instead of shell element to simulate buckling of this type of structure?
Thank you for your insight.

Disk vs blade natural frequencies
I'm trying to determine the coorelation of a blade natural frequency and disk (nodal diameter) natural frequency on a Turbine wheel in ANSYS Modal analysis. Is it possible for a blade natual frequency to be excited even though a disk natural frequency is not being excited?? I'm having trouble determining if a blade frequency is related to any disk nodal diameter. Thanks for any incite on this subject.
FEA Improves Reliability of Flip-Chip Packaging
On Aug 10, 2009, Semiconductor International (SI) Newsbreak published a report on my work in AMD about 3D fracture study of underfill delamination as the top story in that issue. I have never imagined that. Except the pleasure I received from this good news, I wonder if this work is also interesting to iMechanica community. For that reason, I attach here the SI news report and the original paper published on ITherm2008 Proceedings. Welcome any comments and thoughts.

Hello All Dear:
I have a model of the knee with its soft tissue between 2 femur and Tibia Bones, then I want to load 2 boundrical condition
s on it , 1- The 6-DOF's of Tibia and Femur Bones Center of Mass, (x,y,z,R1,R2,R3) time dependent. and 2-The
concentrated load that is exerted on the cross section of the Tibia Shank (Lower Bone) Time Dependent. Then Dear, Can
anyone Help Me,Please how to Put these 2 kinds of Boundrical Conditions on the Model.
Kind Regards.

Hello All,
Actually I am analysing the FEM software FEAP, it is a free FEM software that can be downloaded from:
http://www.ce.berkeley.edu/projects/feap/feappv/
Anyone here knows if the software can run ONLY in cmd ?
I mean, I generate an input file I call the solver than the solver generates an output file without opneing any window in my desktop or in my cmd?
Regards

The residual stress in a metal do not depend on its hardness, but from the module of elasticity or Young module and from its chemical composition (density).
Assigning Hardness to part in Abaqus
Hello Friends,
I am working with abaqus since last year,
I am facing the problem in assigning the hardness property to the material in Abaqus.
If some one knows ,how to Assign a hardness in Abaqus Please let me Know.
