Hi everybody,



I'm trying to simulate the structural behavior of High Performance Fiber Reinforced Concrete specimens by means of the Concrete Damaged Plasticity Model.



My constitutive relation is represented by a multilinear law, with a nonlinear pre-peak followed by a softening branch.



Abaqus UMAT Problem (Fick's second law in Abaqus)

Hello.

     Could anyone tell me how to  achieve the basic unsteady diffusion equation (Fick's second law) of some solute for a given Abaqus model by UMAT & User-defined field in Abaqus? or some other subroutines?

 

    Is there any reference good for this problem ?

 

  Thanks very much!
