How to simulate edge dislocation in Abaqus?

Submitted by hamid.farivar on

Dear All,



I intend to investigate the stress field resulted by a single dislocation in the vicinity of grain boundary at a poly crystalline structure. Thereby, I have to somehow model this crystalline defect, but how? is it doable in the CAE or should invoke the related subroutines?



 Thank you in advance for your tips.

New SIMULIA Tech Brief: Cogging Torque Analysis of Permanent Magnet Machines using Abaqus/Standard

Submitted by SIMULIA on

When designing a permanent magnet machine, one of the most fundamental and difficult goals is to reduce the cogging torque curve. The challenge in reducing the cogging torque is to also decrease the numerical noise generated by the mesh. Finite element analyses and the advanced meshing functionality that is available through Abaqus/CAE allows for a faster and more accurate prototype.

Johsnon-cook model parameter determination

Submitted by psarunirtt on

Hello All!!!

 I am Arun, Master degree student in South Korea.

 My research field is : High strain rate experiemnts

 I did High speed tensile test for aluminium alloy at four different speeds (1m/s, 5m/s, 10m/s and 15m/s)

 I also did high temp tensile test for aluminium alloy at room temperature, 100 C, 250C

 Now i have the stress Vs Strain curve for High speed tensile test and high temperature test

 But, i don't know how to determine Johnson-Cook model parameter from the experimental results
