Necking of a metal dogbone: Large model

This example uses a mesh of the center region of a dogbone specimen, meshed with 7200 C3D8R elements.  This Abaqus/Standard model takes about 91 seconds to run on 1 cpu, or about 60 seconds to run on 2 cpus.   It is always best to understand the model's runtime (suppress field output) before starting a calibration project.  I used this existing model even though I knew it was rather too large for calibration.  Some synthetic test data was created using one particular Johnson-Cook plasticity model.  Then this synthetic data was used to see if the calibration app could re-capture this "right answer" through running a series of Abaqus runs.  


Here is a narrated demonstration video showing this new feature being used in the development version of the calibration app. This video is about 7 minutes long and was created on May 4, 2020.

I revisited this project later in 2020 and took the time to reduce the model size.  See:
