Hello together,
my professor just failed me in an oral exam. It was shwn a graph of a piezometric headline that increased. I said that its because of an increase of the diameter of the tube. He said afterwards:
Dear colleagues,
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 15-19 September 2014. More detailed information on the course is posted at http://mech.fsv.cvut.cz/~milan/course2014.html. We are looking forward to seeing you in Prague!
We are happy to announce an individual scholarship opportunities for international students for studying in International Master Degree Programme Advanced Dynamics of Discrete and Continuum Systems http://imechanica.org/node/16800 of Saint Petersburg State Polytechnical University.
I have difficulty accepting the definition of "nominal strength" and "net strength" given in Shigley's Mechanical Engineering Design.
Consider a plate of width w, thickness t, with a hole of diameter d centered at w/2, loaded with force F.
Shigley's says: the "net stress" is \sigma_net=F/(wt) and the "nominal stress" is \sigma_nominal=F/((w-d)t). ==> I think he is wrong!
According to: http://dictionary.reference.com/
Net:

St. Petersburg State Polytechnic University (Russia) opens a new MSc program in mechanics and mathematical modelling. The program is designed for training highly professional scientists and engineers with the theoretical background and practical experience in theoretical mechanics, computational mechanics, IT, mathematical modelling and simulations, and distributed computing.
Dear all I came up with some stress distributions which exist in a cylindrical specimen in a tensile test. However, I cannot understand how these formulas were gotten. There is a reference to a Bridgman paper (1944). Is there anyone who can give some inputs abouts this?
Thanks in advance

Please join us for a national workshop on Microfluidics and Nanofluidics near Delhi, India during 14-16 July 2014. We are happy to have some higly accomplished academician in multiscale CFD domain. Prof. Suman Chakraborty, Bhatnagar Awardee 2013 will be principal instructor and speaker in the event.

Hi
all,
I
am an ABAQUS novice working on a graduation project. My model is a
reinforced concrete Tee-joint with steel rebars and stirrups embedded to the
concrete. The concrete is modeled using the Damage-Plasticity model, with
mostly default suggested values. The elastic and plastic values are
derived from experimental values. In addition to the embeddment, the
column and the beam is tied together using the tie command. The model is
subjected to an axial load as well as a displacement force.
2.01x: Elements of Structures is a new introductory course in structural mechanics that just started on edX. Anybody can register to audit the course for free.
Course material includes lecture videos, tutorials, example problems, recitation problems with video walkthrough, homework problems, "boardnotes" (condensed lecture notes) and synoptic tables.
