The Fluid Dynamics and Solid Mechanics group at Los Alamos National Laboratory is currently seeking candidates for two post-doctoral positions in the areas of theoretical and computational solid mechanics.
The AMD executive committee (EC) just announced the student travel awards and best paper contest for IMECE 2010. Between 10 and 15 students will be selected for travel grants of $750 each. The students who receive travel awards will also become eligible to participate in the best paper contest. This is a great opportunity for young students to present their work and meet other researchers during IMECE 2010.
A rubber band can be stretched several times its original length. This large deformation may hide its brittleness: the strain to rupture can be markedly reduced by the presence of a crack. This lecture describes fracture mechanic of highly deformable materials, such as rubbers and gels.
Applications are invited for one or more postdoctoral positions at the School of Engineering and Applied Sciences, Harvard University. The projects will be related to elastomer materials with relevance to their optical properties and device applications. Prior hands‐on experience in one or more areas such as polymer materials synthesis, optical measurements, polymer processing is required. The project will have a strong experimental focus and will encompass elastomer processing, physical characterization, mechanics as well as fabrication of devices based on actuation with elastomers.

The research project will be based in the Research centerfor Aircraft Parts Technology in Gyeongsang National University. The researchwill be supervised by a principal investigator of the project (Prof. Jin-HweKweon).
I’m working on optical method for displacement measurement. and this is interesting to know more about application and development of these methods like ESPI , SHEAROGRAPHY anf HOLOGRAPHY . for example i face with a company that climb their product can give displacement and so strain field in many material and many geometry even in 3-D shapes!!
In this recently published paper on Nanotechnology, we studied the in-surface buckling mechanics of one dimensional nanomaterials on elastomeric substrates. Simple analytical solutions are obtained for buckling wavelength and amplitude, which can be easily applied to the in-surface buckling of different nanomaterials, such as nanowires and nanotubes. It is shown that in-surface buckling of nanomaterials has lower energy than out-of-surface buckling, which explains the experimental observance of
The Cardiovascular Biomechanics Lab in the Department of Mechanical Engineering at The University of Texas at San Antonio (UTSA) is seeking a highly motivated postdoctoral fellow to join our research team. The position is supported by a research grant from the NIH to study the mechanical stability and tortuosity of blood vessels. Qualifications include a doctoral degree in BME or ME in computational fluid mechanics, or computational biomechanics.
I have been assigned the task of performing thermal analysis of electronic components that involve conduction and radiation only and determine the temperature distribution on them. I am doing this in ansys workbench 12. Since I am doing thermal analysis for the first time so having problems.
Does anybody have tutorials related to performing thermal analysis in ansys workbench. Please share.
We are seeking outstanding candidates for a Postdoctoral Research Associate Position at the Institute of High Performance Computing, Singapore. The position requires a Ph.D degree in physics, chemistry, materials science, chemical engineering, mechanical engineering or equivalent experience.
In a previous work, substrate-modulated morphology of graphene was analyzed using a numerical Monte Carlo method. Here we present an analytical approach that explicitly relates the van der Waals interaction energy to the surface corrugation and the interfacial properties. Moreover, the effect of mismatch strain is considered, which predicts a strain-induced instability under a compressive strain and reduced corrugation under a tensile strain.
I am teaching Subsea Integrity for the MSc students majoring in Subsea Engineering at the School of Engineering, University of Aberdeen. This is a course that combines the fundamental principles (corrosion, fracture, fatigue and material selection) with the industry applications (subsea integrity management and implementation, cathodic protection, case studies on subsea reliability and engineering assurance).
I have a question regarding Gurson model. If we have a cube with initial length of unit and initial porosity of 20 percent and compress it hydrostatically in order to have a huge volume change of cube, the void growth equation in Gurson model takes a negative rate and reduces the void volume fraction to zero first and further compressing leads to no further void volume fraction change (remains zero) and no more plastic straining. Now let's load the model in tensile hydrostatic state up to a stress free configuration; the void volume fraction of the model remains zero.
I´m facing a problem in which a I´d like to assess stresses due to thermal gradients. I have an IR thermography image (recorded as a matrix) and I like to introduce those temperatures to Abaqus via Matlab.
Is that possible? Or should I use FORTRAN with the UTEMP subroutine?
I modelled soil as non linear springs in Abaqus?Standarads and analysed the pipe behavior for hydrodynamic loading.
I am currently planned to model the pipe-soil interaction with soil as an 2D or 3D element along with contact properties. Give me suggestion or methods how can i model soil.Suggested reading materials.I have gone through the abaqus documentation.It tell that soil can be modeled as 2D or 3D.I am really confused which one to use.
Please give me some steps in creating soil and pipe model .
The interfacial strength is a very important material property for composite materials and other hybrid materials with different stress distributions. Will the interfacial stress distribution have a significant effect on the interfacial strength measurement?
