material TD concrete for nonlinear response

[PriyankaChitrakar]

I gather that for the material "TD concrete" the instantaneous load is allowed only to be applied in a single step and hence it is not possible to get data to form a short-time loading curve. Is there a way to get the data?
Also, if the short time load applied is such that it exceeds the elastic limit, since the load is being applied in a single time step, will the program consider the nonlinearity of the concrete?
