Description
User-defined material script (UMAT) script for Abaqus, polycrystalline shape memory alloy model
For modelling a polycrystalline shape memory alloy wire
It refers to the model published in paper ...
The number of state variables NSTATV in Abaqus must be twice the number of crystal orientations
For example, NSTATV = 2 is a SMA monocrystal
The material properties in Abaqus must be set as follows :
PROPS(1) : Young's Modulus
PROPS(2) : Latent heat parameter
PROPS(3) : Reference temperature
PROPS(4) : Dissipation parameter for self-accomodated martensite
PROPS(5) : Dissipation parameter for oriented martensite
PROPS(6) to PROPS(5 + NSTATV/2) are the values of the maximum phase transformation strains
