Concrete plastic deformations without Geomechanics Module

Hello, I’m new to COMSOL and currently trying to perform a flexural analysis of a concrete beam. I would like to ask whether it is possible to accurately model the plastic (nonlinear) behavior of concrete without having access to the Geomechanics Module. From what I have read, the Smeared Crack Model and Damaged Concrete Model are available only through the Geomechanics Module, while the default material models such as von Mises or Tresca seem to be more suitable for metals, not brittle materials like concrete. Is it possible to simulate plastic deformations or cracking in concrete using only the Structural Mechanics Module, or is the Geomechanics Module required?
Thank you for your help
