dear iMechanica friends



I came across a review of a paper by HD Bui who was somewhere in the internet, and I find it is very interesting. I could even have written this review myself !!  I don't think the reviewer exaggerates....

Hello everyone:

1.  I have built a FEM model 2D plane strain using ABAQUS/Standard (CPE4R) elements,

2. I am  modeling the contact between a cylinder and a plate in 2D.

3. The Cylinder material is given is ELASTIC ISOTROPIC material with no plasticit E=310 GPa

4.  The plate is with a Ramberg-Osgood plasticity with a Young's modulus E=210 GPa.

5. The mesh at the the contact point is VERY refined element characteristic length is about 1 micron. (My model units are  (mm,N,sec)).

I am delighted to announce on behalf of Elsevier that Professor Michael Ortiz of CalTech has won the very first Rodney Hill Prize in Solid mechanics in reconition of his body of research during the decade 1998-2007. The prize will be presented at ICTAM in Adelaide on 27 August by Y.S. Chi, Vice Chairman of Elsevier immediately prior to Michael's Hill Prize lecture.

Two four-year PhD positions are available in the area of computational mechanics at the Materials Science and Engineering Department of Delft University of Technology. The job descriptions are attached.

You may remember that I promised some time ago to discuss each of the topics mentioned by Ken Johnson in his Timoshenko Medal speach. Here I take rail corrugation. Rail corrugation has been noticed at least for 100 years, but (particularly short pitch one in the range 20÷80 mm) has been considered an enigma because measured corrugation wavelength did not relate well with wear instabilitymodels.
