We seek a highly qualified applicant for a post-doctoralresearch position in experimental mechanics and materials.The successful candidate will designand conduct experiments establishing mechanical properties of thin polymerfilms and layered composite materials at a range of temperatures and humidityconditions. The project aims towards improving the durability of polymer fuelcells and is funded through DOE. Funding for this position is availableimmediately for a period of one year and may be renewed thereafter.
I am planning to perform few "true-strain-rate" experiment under compression (where the crosshead velocity is not constant sice the height of the specimen keeps decreasing/ area of cross section keeps increasing, hence requiring the velocity to decrese to attian true stress-true strain), is there any option available in Bluehill or Max software of Instron 8874to suit my requirement? As an alternative method, are there any options for me to import my own X-Y data (either time vs position or time vs velocity) to the system so that i can perform this true strain rate testing.
Ferroelectric nanotubes have potential application in inkjet printing and drug delivery due to their piezoelectric property and unique geometry. For different applications, different electrical boundary conditions are applied to ferroelectric nanotubes. In the present work, domain structures in ferroelectric nanotubes (FNTs) under different electrical boundary conditionsare predicted through a phase field model.
I joined imechanica almost a year ago and I've been frequently following its interesting discussions, even the most animated ones. I think that a place like this is ideal to foster the exchange of ideas in the scientific community;
Moreover it is fantastic as a simple student like me can interact and easily ask questions to the most important researcher in the field of mechanics.
Spring 2008: The Materials Division of ASME is pleased to announce the creation of The Sia Nemat-Nasser Early Career Medal in honor of Dr. Sia Nemat- Nasser, Director of the Center of Excellence for Advanced Materials at UC San Diego and Distinguished Professor of Mechanics and Materials. This award is given to recognize research excellence in the areas of experimental, computational, and theoretical mechanics and materials by young investigators who are within 10 years after their Ph.D. degree, with special emphasis placed on under-represented minorities and women.
I am a new comer here and I need some help. I want to simulate the interface debonding process of bimaterial using the commercial FE software msc.marc, but I want to use my own cohesive law not the one given by the marc. so the user subrotine UCOHESIVE must be used, the problem is I dont know how to program using FORTRAN. I hope some one here can help me, if you have such a user subrotine, can you kindly sent it to me? that will give me a great hand. Thank you very much. Expect your reply.
I'm looking for finite element formulation for
buckling (or vibration) of an axisymmetric plate. i went threw the whole
shelf in the library and didn't find something that i can implement
or reference for a software i can integrate with matlab. i will be
grateful if you could point me in the right direction.

A postdoctoral researcher position is available at the Solid Mechanics Laboratory at Ecole Polytechnique (Paris). The aim of this postdoctoral research project is to investigate the mechanical behavior of a newly-developed all-metal sandwich sheet material for automotive and aerospace applications. The ultimate goal is to optimize the characteristic sandwich core structure for formability, crashworthiness and fatigue life. This research makes use of experimental, theoretical and computational mechanics.
I have a question in my mind, we all know that the fracture toughness of isotropic, homogeneous materials is dependent on state of stress (plane strain and plane stress). It is higher in case of plane stress and decreases as the constraint increases and attains a constant value which we call "plane strain fracture toughness". But, what about the fracture toughness in interfaces? or fracture of thin layer bonded between two substrates (adhesive type)? I am sure that it will be a function of this as well.
I would like to bring to your attention the advanced course on Modeling of localized inelastic deformation that will be taught by Milan Jirasek in Prague, Czech Republic on 22-26 September 2008.
More detailed information on the course is posted at http://mech.fsv.cvut.cz/~milan/course2008.html. We are looking forward to seeing you in Prague!
The lecture notes of the two courses I taught at Stanford University during the last two quarters, "ME 340 Elasticity" and "ME 334 Introduction to Statistical Mechanics", are available in PDF format online at:
