Two faculty positions at Assistant/Associate Professor lavels are open in the School of Aeronautics and Astronautics at Purdue University, West Lafayette, IN (https://engineering.purdue.edu/AAE). The positions are open to all specialties complementary to current AAE research areas.
Hello, a simple question about the Lagrangian and Eulerian descriptions of fluid flow.
When is the Lagrangian (particle point of view) useful? It seems
that the Eulerian is always the right one, since velocity and pressure
are fields.....
thanks !

Hi everyone!
I'm brand new of this website, but I'm already very excited about it - it's really helpful.
hi, i am currently working on using abaqus software for solving sintering problems . i just want to know how i can introduce new parameters into abaqus so that by giving some eqns for those i can solve the values of final porosity, shrinkage etc that are not pre-determined in the abaqus . i want to know the porosity distribution and shrinkage rate in a particular given problem as outputs . please help me out . thnq
Hello everybody,
In the implementation of nonlinear FEM, there are two ways, namely the Voigt notation and the full matrix notation. Obviously, using Voigt notation, one only stores vector instead of matrix. So, by using the symmetry of the Cauchy and second Piola Kirchhoff stress tensors, it is always possible to implement nonlinear FEM using Voigt notation.
So, my question is why the full matrix implementation still exists? It is mentioned in the famous book of Ted Belytschko. Only due to historical reason or there are some advantages?
The Johns Hopkins University, Department of Mechanical Engineering, invites applications for a full-time tenure-track faculty position in the general area of mechanics and materials. Modeling and simulations are of particular interest, but all outstanding candidates will be considered.
Hello all,
I'm modeling the railways track system, in which the rail wil be affixed to the cross tie by Fastening to against the vertical force.
Now instead of modeling the Fastening, I would like to model the contact between Rail and cross Tie in ABAQUS. I have try surface to surface; surface to node and also tie constrains, but somehow the results are not reasonable (not agree to experiment result). I thinks the problem is contact properties.
So are there any one can helo me on the problem?
A post-doctoral position is available in the area of material modeling of composite at the University of New Brunswick, Fredericton, Canada. Particularly, expertise is sought in finite element simulation of damage/fracture and thermomechanical properties of fiber composite. Experience in multiscale finite element modeling of fracture and damage behavior of composite materials is required.
