Hi,
In my project, I have to extract the stress results in the last step of simulation and then use theses values in some equations and overwrite the calculated values as the initial stress (S11, S22, S33, S12, S23, S13, Mises) for the following simulation. Anybody can help me please?
Thanks.
Hi Majid, you can certainly work out with user material subroutine, UMAT where you can include your own constitutive equations to calculate the values, and then pass it to ABAQUS. However, depending on your model, the process can be very easy to very hard. You can find more information here: http://imechanica.org/files/Writing%20a%20UMAT.pdf
Hello Majid, you can define a user subroutine as Mr. Choudhury said or you can define a path from your last step and then report XY-data then export it to an excel file where you can define your equation and calculate what is required from there.
Many thanks Soud and Tamer. After extracting the excel file how can I overwrite the new values on the previous values of stress and export as an initial stress for the following analysis?
