Hi Claudio,

Thanks a lot for your answer.

I'm doing an explicit dynamic analysis and in this scenario, is it possible to define ALPHA and BETA coefficients for materials?

As you mentioned, in transient structural analysis material damping can be defined using ALPHA and BETA coefficients.

Thanks a lot for your ideas.

I'll check whether my model can be developed in transient structural analysis to obtain the required results.

Thanks again for your kind concern.
