The University of Exeter will shortly announce several new chairs it is seeking to fill.
The chairs are full tenured chairs and in the following areas -
Cell Mechanics (two chairs, one nominally experimental and one nominally theoretical).
Structural Dynamics, possibly with an aerospace flavour.
If you are interested, or know someone who might be, please contact me (c.w.smith-at-exeter.ac.uk) for an informal discussion.
Regards,
Chris Smith

In 2010, Yves-Patrick Pellegrini published a paper in Physical Review B called
Dynamic Peierls-Nabarro equations for elastically isotropic crystals. with the abstract
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?
George Bugliarello, president emeritus and former chancellor of Polytechnic Institute of New York University (NYU-Poly), an acknowledged visionary who brought about significant changes in engineering and education, died after a short illness on February 18. He was trained in hydrodynamics and civil engineering. His lifelong investigation was how natural, mechanical, information and energy systems affect society.
hi all,
I am facing problem in understanding stress intensity factor. How exactly i can analyse crack propagation through SIF. In books it is given that SIF characterises the crack. But in numbers how can i know whether this crack will propagate for this value of SIF. According to westergaard equation crack tip stresses will go to infinity if θ and r tends to zero for any value of crack length. Please somebody help regarding this. If iam technically wrong please correct me.
Thank you
Kirthan.L.J
