Hi Everyone,
I have written Drucker Prager in VUMAT version as shown below..but still there are some deviation with the original in built version of ABAQUS. I have all the notes how i derived these equation.could you please show me where the code has gone wrong or have i missed a critical point in here..i tried my best to spot the error but could not..may be you all experts could find it. Thank you very much.

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/

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
