hi all,
i am very new to abaqus and i want to simualte sliding wear between a pin and a disc. i found from the literature that by using user subroutines we can calculate the wear. i am not getting how to use a user subroutine , can any one expain how to use user subroutines in the CAE. is there any simple example problems in understanding this user subroutine functions. thanks in advance.
Hello everyone,
I am currently writing a UMAT for non-linear viscoelastic materials. In order to do some verifications,
I need to be able to customize the time incrementation scheme. For example, the first increment would
have a time step of 1E-5s while the other increments would have constant time step of 1E-2s. I know this is not a
very straightforward problem, but I really need to be able to do that. I am currently trying to combine my UMAT with other subroutines
The Joint Research Centre of the European Commission,Insitute for Energy (IET), in Petten Nehterlands, is looking for a motivated scientist or engineer at post-doctoral level to work on characterization of primarily metallic materials for nuclear reactors using a combination of techniques such as scanning and transmission electron microscopy (SEM and TEM), energy-dispersive X-ray spectroscopy (EDX), Xray diffraction (XRD), and 3D X-ray tomography.

Postdoctoral positions are currently available at MIT's Department of Materials Science and Engineering for individuals with a strong background in materials simulations. Experience in atomistic methods (both classical potential or first principles) or mesoscale methods (e.g. phase field or dislocation dynamics) is preferred. Projects will focus on several different aspects of grain boundary and heterophase interface properties in metals. There are no citizenship requirements associated with these
The objective of the workshop, co-organized by Joint Research Centre of the European Commission and Middle East Technical University, is to discuss the present status of physics based constitutive modelling of metallic materials and associated experimental methods.
The Workshop is funded by the European Commission's Integration and Enlargment Programme. There is no cost for attending the Workshop. A limited number of scholarships is available for participants from the target countries (see attached flyer).
The Computational Bioengineering Group in the School of EPS at Heriot-watt University, UK has three PhD studentships available.
*Please check following details before apply as they have different values and application procedures as well as closing dates.
*Please indicate which studentship you are interested in when making the informal enquiry to Dr Yuhang Chen (y.chen [at] hw.ac.uk)

In addition to the ASME awards related to the Applied Mechanics Division, some prestigious society awards will be given to mechanicians at the IMECE, Houston, Texas, in November 2012.
Professor Jan Achenbach of Northwestern University will receive the ASME Medal. [ASME Medal, established in 1920, is the highest award that the Society can bestow and is to recognize “eminently distinguished engineering achievement.” Only one ASME Medal may be awarded annually.]
