Quantifying dislocation microstructure evolution and cyclic hardening in fatigued face-centered cubic single crystals

Submitted by ahmed.hussein on

Discrete dislocation dynamics simulations were performed to investigate the dislocation microstructure evolution and cyclic hardening during the early stages of fatigue loading in nickel single crystals. The effects of the crystal size and initial dislocation densities on both the mechanical response and the evolution of dislocation microstructure were quantified. Crystals having an initial dislocation density of 1012  m−2 and diameter less than  do not show any dislocation density multiplication or cyclic hardening.

Who should attend

positions available for PhD students, visiting students, or visiting scholars

Submitted by songbai on

We have PhD student positions available who are interested in soft tissue biomechanics of the brain. Work will involve developing sophysticated, yet efficient computational models of the human brain to study the mechanisms of brain injury. This work is supported by NIH grants.

In addition, we have openings for visiting students or visiting scholars who have their own funding to stay in the lab. 

Interested applicants please contact: Songbai.Ji [at] dartmouth.edu

For visiting positions, please clarify your funding sources and the eligibility to work in the lab.

Finding drag and lift coefficients using Ansys APDL and/or fluent?

Submitted by amin013 on

Basically, I want to find the lift and drag coefficients for a fluid (air) flowing over a prismatic triangular cross-section, any suggestions, where  can I find some tutorials to begin with.

After I get started, I'm interested to find those coefficients for different angles of attack.

Hi friends;

I have three volumes with different materials, I want to define material properties for them in workbench 14, but acp module isn't in it. 

How should I define material properties for every layer from volume? Is any way in workbench14 or I should install workbench 15?

my model in workbench is below:

please help me.

Regards.

Simulation of surfaces interaction in 2d model in Abaqus

Submitted by Anthos on

Dear Subscribers 

I am a new abacus user and I am trying to simulate the interaction between two

the surfaces of 2 different parts and materials. Does anybody knows how can I proceed 

in this simulation procedure. With pleasure any answer will be helpful from my work.

Thank you in advance
