How to modify the dislocation density-based constitutive model to incorporate solid solution and second-phase strengthening

[Brian-Liu-rx]

Hi, everyone,
I would like to modify the algorithm of the dislocation density-based constitutive model. My objective is to explicitly incorporate the contributions of solid solution strengthening and second-phase strengthening into the critical resolved shear stress (CRSS), alongside the dislocation density strengthening term. What is the general roadmap for achieving this, and which specific files (subroutines) need to be modified?
