Hello
can anybody explain about "Inertia relief" and its practical significance?
Also i read from nastran mannual that it calculate rigid body acceleration , how do we get rigid body acceleration bcoz in inertia relief static analysis we fixed the all possible rigid body motion .
Please share the information on this
Thanks and Regards

An electronic device integrates diverse materials, and inevitably contains sharp features, such as interfaces and corners. When the device is subject to thermal and mechanical loads, the corners develop intense stress and are vulnerable sites to initiate failure. This paper analyzes stress fields at corners in flip-chip packages. The stress at a corner is a linear superposition of two modes of singular fields, with one mode being more singular than the other. The amplitudes of the two modes are represented by two stress intensity factors of dissimilar dimensions.
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.
Dear Sir.
Greetings!
I believe my strong academic background, personal initiative, and work experience would be an asset to my Future research work and also for my Dream career. As indicated in my resume, I have Sound knowledge in Modeling and Analysis Packages, Auto CAD, Pro-Engineer wild fire, Pro-Mechanica & ANSYS
Hi all
Can anybody help me out in modeling weld induced residual stress in a plate structure.
many thanks

Dear All.
I am looking for a sample code demonstrating contact algorithm in finite element methods. Any help will be greatly appreciated!
The NSF Major Research Instrumentation Program (MRI-R²) Recovery and Reinvestment is now posted. This is a good way to build up the needed major research instrumentation
The deadline for proposals will be August 10, 2009.

Does anyone knows where I can find any paper discuss the existence of potential functinoal for materials that violate the maximum plastic dissipation principle (due to non-convex yield function and/or non-associately fluw rule)?
Hi I'm trying to work out the following problem
The pressure at the start of a 180Km stainless steel natural gas pipeline is 4MPa and at the end is 2MPa. If the diameter of the pipe is 0.4m, what will be the gas flow rate through the system? (ignore losses other than friction)
(for natural gas, density = 40 Kg/m3, viscosity = 11x10-6)
This is from an exam paper and at the end of the paper there's a moody diagram with roughness values, the closest to stainless steel is commercial steel and has a k value of 0.045 mm.
