Hello Friends,
I’m trying to simulate a tensile test for an elastic-perfectly plastic material in Abaqus Explicit. I have solved the same problem in Abaqus Standard and the results were very good as follow.
In Abaqus Explicit I have a problem which is the trend of the stress-strain is not elastic-perfectly plastic like in Abaqus Standard. In Explicit the load arrived to the yield point and then released instead of going constant when the strain increases as you can see in this image.
As you knew that in the elastic-perfectly plastic material the stress and strain increases up till the yield point then the stress become constant however the strain increase.
This trend I got from standard. However in explicit the stress arrived to the yield point (the same point exactly) like in standard then suddenly go to around zero stress vertical and then the strain increases again under (around zero) stress.
Cand you explain to me how to solve this issue in Abaqus explicit however I used the same parameters like in Abaqus standard but I don’t know why this happened.
Thank you,
Obesco
