Dear All,
These days I am do some research on vibration of circular plates (out-of-plane and in-plane). In the reference, the displacement in radial direction can be expressed with Bessel polynomial. I want to use the Rayleigh-Ritz method to solve these problems. The strain energy and kinetic energy can obtain with integral. If there is the bessel function, how to calculate the integral. Also I want to consider some spring in the boundary to change the boundary conditions.

Two PhD positions are available to work on corrosion of aluminum and steel. Students are expected to study "how corrosion affects the microstructres in the metal and alloys".

Positions are available in world's leading research laboratory. Interested students may contact on the following website:

how to do a crack propagation analysis?

can abaqus be used for doing crack propagation analysis for plates with multiple cracks?

Dear Colleagues:

We are currently soliciting abstracts for the 2012 ASME IMECE conference on November 9-15, 2012 in Houston, TX.  The symposium is entitled Quality and Reliability of Electronic/Photonic Packaging, MEMS, and NEMS and is part of the Micro- and Nano- Systems Engineering and Packaging Track.

The call-for-papers for the symposium is as follows:

dstl PhD studentship: Electropulsing and nanostructured steels

Imperial College London - Department of Materials

Duration of Studentship: 42 months

Applications are invited for a studentship in the field of electropulse-assistant nano-steel processing, leading to the award of a PhD degree. The post is to conduct research in the Department of Materials at Imperial College London and is supported by an initial bursary of £15,823 p.a. and the tuition fees are paid at the home rate only.
