define material mass density variable with loading process

      How can I use UMAT subroutine to define a material whose mass density varies with the loading process?

      The current density is available in common block aux35loc (search dyn21*.F), but I don't think it can be changed in a way that will affect the mass calculation. Moreover, I don't think it's possible to access loading conditions from the user material routines. So I don't think it is possible to do what you are looking to do.

      Thank you, is there any other way to implement this feature?
