the damping in the umat of abaqus
Hi all,
I find that the umat in Abaqus doesn,t support the stiffness damping. How can I introduce the stiffness damping into my subroutine?
Thank you very much!

Post-doctoral Positions in Ultrasonics at the Ohio State University
Post-doctoral positions are available in the area of ultrasonic material characterization and nondestructive evaluation (strong background and experience in ultrasonic experiment and modeling are required). The positions are supported from research grants and are intended for several years. The focus area is ultrasonic study of nonhomogenous materials like composites, adhesive bonds and polycrystalline materials. State of the art ultrasonic laboratories and other characterization facilities are available. More details will be provided to interested individuals.
Doctoral (PhD) studentship available in Utah State University for Spring 2011
There are several fully funded graduate student openings starting Spring 2011, in the
Department of Mechanical and Aerospace Engineering at the Utah State
University (http://www.mae.usu.edu).
The openings are in the broad area of Computational Solid Mechanics. In
particular, applicants having demonstrated interest (in terms of
completed projects, authorship in journal articles or coursework) in
Fracture Mechanics are especially invited. Applicants are requested to
Scale of mechanical systems and force-displacement relation
I have a question which has kept my mind busy recently. Assume that we have a system of two masses (m) as shown in the figure. The force (F) results from the gravity force between two masses (m) apart at distance (d), and is applied on a bar with modulus of elasticity (E), length (L), and cross section (A). Assume two pictures are taken from this system from two different distances. So, although the two pictures show an identical system, one of them looks smaller in size compared of the other one.
Solver for XFEM
In the FEM book by KJ Bathe and also in the fem book by G.Dhatt, it is said the direct solvers are generally more convenient than iterative solvers and new versions of them include reordering and efficient use of skyline method. In contrast there are iterative solvers with capability to directly manipulate sparse format of matrices. I am now working on XFEM coding with C++ and don't know what type of solver would be the best for XFEM. the conditioning issues of matrices obtained from XFEM would be a difficulty for the choice of preconditioners.
Introducing a user defined heat flux to ABAQUS
Dear all,
I must apply a user defined heat flux to ABAQUS for getting thermal profile in defferent nodes and elements. How can I apply this user defined heat flux to AVAQUS and how can I write this user defined heat flux for ABAQUS?

Detonation &knocking
hello dosto,
i am studying in B-tech 2nd year (mech.) in DCE . I want to know about detonation and knocking of fuels in detail.
thank you

Elementary Mechanics and Basic Engineering Thermodynamics
I suppose it is acceptable to announce the work I have online to assist students in learning mechanics and thermo. The site is http://www.askdrthermo.com/. Please take a look if you are interested.
