Replacing material model parameters with non-linear equations

  Is it possible to replace parameters in a material model with a user defined equation and if so what is the best way of going about this? To give a little more context, I am currently working on a problem involving projectile impact on fibre reinforced concrete. I'm predominantly using the RHT concrete model to simulate the material behaviour, but I would like to incorporate a dynamic increase factor to the tensile strength, replacing the tensile strain rate exponent. The dynamic increase factor would be a non-linear equation and needs to be able to take other outputs from the model such as strain rate. Is there a viable way of doing this in explicit dynamics?
