Job title: JRF
Minimum qualification: MTech in Mechanical/ Applied Mechanics or Equivalent.

Two PhD positions are currently available in the Computational Laboratory for the Mechanics of Interfaces at the University of Tennessee - Knoxville (http://clmi.utk.edu). Research topics are in the following areas:
1. Modeling of titanium alloys using dislocation density based crystal plasticity finite element method.
2. Thermo-mechanical modeling of damage in fiber-reinforced composite materials using mixture theory.
In a cooperative research between PoliMi and UIUC we have analyzed the crack growth in Ni-based single crystals:

Crack growth experiments analyzed with DIC had shown relatively low closure levels respect to polycrystals. Crystal plasticity simulations with WARP3D have been able to simulate closure levels consistent with the experimental ones.
A PhD research subject is proposed for students to apply at Arts et Métiers ParisTech.
Hello everyone!
My goal is to model large plastic deformations of polycrystalline metals using crystal plasticity and ALE adaptive meshing. In order to do that I want to use VUMAT subroutine in Abaqus/Explicit, since as far as I understand Abaqus/Standard is not good for large deformations and it doesn't support ALE adaptive meshing for that purpose.
The ability of scientists and engineers to exploit, design and process new materials with improved properties has often been fundamental for the technological advances of societies. In fact, advances in many key domains like aerospace, automotive industry, energy, nanotechnology, rely on our ability to engineer new materials and to exploit their properties. For metallic materials, such technological advances usually requires a deep understanding of how mechanical and physical properties are influenced by microstructural features (e.g. grain size, crystallographic orientation).
We have an open PhD position starting in either the Spring or Fall semester 2016 at the Computational Laboratory for the Mechanics of Interfaces at the University of Tennessee - Knoxville (http://clmi.utk.edu). The research topic centers upon the modeling of texture evolution in FCC and BCC metals using dislocation density based crystal plasticity.
We have two research positions, available in November 2015, in the area of micromechanics of advanced structural steels. The first one is a post-doctoral research fellow (RF) position. An ideal candidate for this position must possess a PhD in mechanical engineering or related field with a strong background in computational materials mechanics. Experience of developing mesoscale methods such as dislocation dynamics or crystal plasticity and mesoscale fracture mechanics will be a definite plus.
Applications are invited for three PhD positions within the Cognitive Performance Optimization Laboratory (COPOL) in the Department of Mechanical Engineering at the University of New Brunswick.
Hi!
I am just a beginner in Abaqus UMAT and I have started working with Dr Huang's crystal plasticity UMAT in Abaqus.
When I am assigning one material constants for one element crystal it works but when I try to assign it to more than one element for one crystal (for example group of elements with same grain orientation) it give me error code 144.
Can anybody explain me the reason?
Thanks in advance,
Kind regards,
Omid
