Finite Element Method

Dear All,

I am currently working on a small academic project of Damage Detection of Bridge Structure using Vibration Frequency and Modes analysis and Finite Element method.

My questions are:

1) Is there any systematic approach to follow this problem?

2) How should I start making its mathematical model? I am considering a truss bridge. Is it appropriate to consider linear elastic deformation of simply supported beam at first point?

3) Is there any standard reference which can help me to construct its mathematical model?

The Fluid Dynamics and Solid Mechanics group at Los Alamos National Laboratory is currently seeking outstanding candidates to fill a post-doctoral research position in computational solid/structural mechanics.

The prospective candidate is expected to take part in the development of non-classical, global-local plate/shell finite elements for applications involving the response and/or failure of composite structures under severe dynamic loading conditions.

Distribution of electromechanical field near electrode tips is closely related to the reliability of ferroelectric multilayer actuators. In this paper, the deformation and stress concentrations around the electrode tip in two multilayer actuator designs, partially and fully cofired, are investigated by means of experimental measurement and numerical simulations. The digital speckle correlation method (DSCM) is used to measure the full displacement field near the electrode tip with the high spatial resolution.

I thought the mechanics community would be interested in the course notes of

Prof. K. J. Bathe on "Finite Element Analysis of Solids and Fluids". This

course was taught at MIT and now is available freely through MIT Open

Enjoy!
