A 3D Social Net Working Site (http://bit.ly/9yGMrO) was launched for publishing 3D Simulations.  It is to 3D Simulations like what youtube is for videos. The teachers / Professors of Science , Engineering, FEA, CFD can download the 3D simulations from here and embedded into PowerPoint slides and show interactive 3D simulations to the students, making the teaching of Science and Engineering very interesting. http://bit.ly/9yGMrO   

Dear colleagues,



The Journal of Solid Mechanics (JSM)  invites original research papers and research notes covering a broad area of mechanical engineering activities associated with the classical problems of structural analysis to mechanics of solids, fracture, and heat transfer, thermal effects in solids, optimum design methods, and numerical techniques and recent developments in these areas for review and consideration of possible publication.

Dear Friends,

I would like to know if there are any element in abaqus which may be used at the contact interface to account the frictionalal behaviour. I would appreciate if you show light on this.

Thanks and Regards

Distribution of electromechanical field near electrode tips is closely related to the reliability of ferroelectric multilayer actuators. In this paper, the deformation and stress concentrations around the electrode tip in two multilayer actuator designs, partially and fully cofired, are investigated by means of experimental measurement and numerical simulations. The digital speckle correlation method (DSCM) is used to measure the full displacement field near the electrode tip with the high spatial resolution.

Abstract

Bacterial outer membrane porins (Omp) that have robust ß-barrel structures, show potential ap-

plications for nanomedicine devices in synthetic membranes and single molecule detection biosensors.

Here, we explore the conformational dynamics of a set of 22 outer membrane porins, classified into

five major groups: general porins, specific porins, transport Omps, poreless Omps and composed

pores. Normal mode analysis, based on mechanical vibration theory and elastic network model, is
