Post doctoral associate or post-graduate researcher position is available in the Department of Civil Engineering at the Catholic University of America ,Washington, DC. The candidate should be proficient in C++ programming and OOP concepts and preferably (but not necessarily) GIS applications. PhD degree is not necessary. The project involves developing an agent-based fish life cycle model for San Francisco Bay and Delta. The initial appointment will be for two years with the possibility of extension based on satisfactory performance.

Thermal Ratcheting in Cylindrical tubes

Submitted by unsrohith on

Hi ,

Due to  Thermal ratcheting in cylindrical pipes carrying hot fluids that are used in nuclear applications, the pipe bulges. I am about to start a project to study why this bulge comes and how to rectify it. It would be very helpful to me if  some of you can give your valuable suggestions and references in the area of Thermal Ratcheting in pipes.

Thanks and Regards,

Rohith   

Effect of Fiber Geometry on Pulsatile Pumping and Energy Expenditure

Cardiac Mechanics

Myocardial fiber orientation is a topic that has recently received much attention in connection with cardiac pumping function. The twisting motion of the cardiac base to apex can be a direct result of this geometric orientation of these fibers. One important question that has not been addressed yet is whether there is any relationship between the contractile energy expenditure and the geometric orientation of myocardial fibers. In the present work, we study the effect of contractile fiber orientation on pumping function.

Strain Based Fracture Mechanics

fracture mechanics

Hi!

I`m new to this webpage, and hope for some good answers for use in my masters degree within fatigue. Currently I`m working on calculating the total life of a gusset specimen using strain based fracture mecahnics. I`ve read som articles on the topic, but have some difficulties on understanding the calculations itself. I`m using Excel in the calculations. If anyone has an excel-sheet, or other ways of helping me, I would hihgly appreciate it.

Thanks, Sean Angus

Inertia relief in static analysis

Inertia relief

 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

Singular stress fields at corners in flip-chip packages

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.
