Same with what? In material part of abaqus for damping a constant amount for alpha, beta and ... can be applied. How should i define this curve in that part?

Victor J. Аdlucky

If I understood the manual correctly, this can be done only in Abaqus/Explicit via user subroutine VUSDFLD. More detailed information is given in *DAMPING https://www.sharcnet.ca/Software/Abaqus/6.14.2/v6.14/books/key/default.htm and sect. 1.2.22 https://www.sharcnet.ca/Software/Abaqus/6.14.2/v6.14/books/sub/default.htm The example in the second link can be used as a sample.
