Research Scientist at TU Bergakademie Freiberg
A research scientist position is available at TU Bergakademie Freiberg in the area of computational modeling of dislocation properties using either molecular dynamics, discrete dislocations or crystal plasticity. The research of the group focuses on dislocation properties at both the nanoscale and the microscale. The successful candidate should have a strong background in numerical modeling with demonstrated capability of innovative and independent research.
Do you care about the impact factor of the journal when you submit your article??
just a friendly question to all of you....
what is your opinion on the journal impact factor...
i personally think is very superficial and skin deep beauty. but i want to know your opinion.
thanks

What is the reason behind the nonlinearity in the stress-strain curve of elastomers(Molecular Level)
return map algorithm
Dear all,
I am trying to code a UMAT subroutine for perfect plasticity with a Tsai-Wu failure surface. I follow the procedure of the closest point projection in Simo & Hughes, Box 3.5, which is quite straight forward. At least I thought so
The algorithm converges but unfortunately not to the correct point in the (plane-stress) stress space. At first I used an yield surface wich gives a unit sphere in the stress space. It is easy to control the normality of the plastic strain increment and the return-map algorithm is implified to a radial return algorithm.
