Iain Finnie passed away in December. At the time he was the James Fife Professor Emeritus U.C. Berkeley Dept. of Mechanical Engineering.
Iain had an amazing number of contributions spanning diverse area of mechanics. To the best of my recollection:
He published some great early work on the shear angle in metal cutting in 1953.
He published the first book on creep in 1959 with William Heller.
He published a (the?) pioneering paper on erosion in 1960.

Closing date for receipt of applications: 30 January 2010You will join a research project “Optimise blast resistance of novel composites made with fibre metal laminates (FMLs)” sponsored by the Leverhulme Trust. The project will be jointly supervised with Prof. Cantwell who is an expert on testing of novel composites. The project is to develop comprehensive finite element models capable of simulating various deformation and failure modes relating to composite features of FMLs subjected to extreme loading conditions.

Hi,
I have a structure which is made up of continuum elements and beam elements joined together. I tried to join the beam elements to continuum elements by tie and coupling (I tried both distributing and kinematic coupling).
There are 2 general-static steps, first a vertical load and then a tip load. For both tie and coupling approach, Abaqus Standard give me aborted runs because the time increment is too small. I tried all ways of stablization but it still would not run.
Definitively solved the problem of measuring residual stress in metals. No more expensive equipment: x-rays. neutron, ultrasound is not reliable, or destructive stain gauge and all equipment or modal analysis that are not absolutely precise and safe
A new discovery has resolved the problem exclusively with the principles of applied mechanics.
A research position at postdoctoral level is currently available in the School of Civil Engineering at the University of Sydney. The position is full-time fixed term for 2.5 years; further extension may be possible depending on the performance and availability of funding. The appointee will be working in a project funded by the Australian Research Council on the study of quasi-brittle fracture. Briefly, the project aims at understanding fracture and fragmentation processes in quasi-brittle materials, which is critical to the prediction of natural catastrophes and structural failures.
It is well known thatdislocations in FCC metals are composed of partial dislocations separated bystacking faults. When consideringthe reactions of dislocations with each other, such as in DD simulations, it is necessary to determine therelative positions of the partials in order to correctly describe theconfigurations that are created in the reactions. Here we describe a geometric method for correctly determiningthe relative positions of the partials. The results we obtain can also be found by applying an axiom, or rule,given in the book by Hirth and Lothe. At the end
The Department of Mechanical Science and Engineering at the University of Illinois, Urbana-Champaign is actively seeking candidates for faculty positions in all areas of mechanical science and engineering. Please see the official announcement below.
I am working on a project "vehicle ride dynamics using component mode synthesis." I would be making a matlab code to determine the vehicle body response due to road excitation signals. I will be modelling the tyre stiffnesses using springs, suspension with springs and dampers and vehicle body using plate of varying stiffnesses. I want to know that how a vehicle body can be approximately modelled with a plate of varying stiffnesses so that it reflects the real car body, as just assuming it as plate( of constant stiffness) will be too crude approximation. Also i woluld like to compare various CMS methods like free interface, fixed interface, hybrid interface on this system. If anybody has done any work in this field please provide some guidance.
