Shape memory alloy material models including plasticity implemented in ABAQUS
I am working with shape memory alloys (nitinol), and am in that respect investigating fracture behaviour of NiTi, using, among other things, simulations in ABAQUS. ABAQUS doesn't have a material model that include plasticity unless you pay for it. I am wondering if anyone have implemented either of the following models as a UMAT, and if you are willing to share the code with me.
The models I am interested in are:

fatigue crack growth
Having glanced at the web site I can see that it might be useful to shed some light on fatigue crack growth and crack closure based concepts.

The effects of boron dopings and boron grafts on the mechanical properties of single-walled carbon nanotubes
The effects of boron doping and boron grafts on the mechanical behaviour of armchair (6, 6)
and zigzag (10, 0) single-walled carbon nanotubes (SWCNTs) under axial loading are
investigated using the molecular dynamics (MD) simulation method. The results show that
Young’s moduli, the tension strength, the buckling loads and the buckling strains of SWCNTs
decrease after functionalization. The influences of the distribution density of functionalization
on Young’s moduli of SWCNTs are also systematically studied. The results show that Young’s
