When Lagoudas is selected from the
Shape memory alloy model list, the
Phase Transformation Direction node is automatically added to the
Shape Memory Alloy node. Since in many applications the transformation direction
is known a priori (for instance, mechanical loading or unloading, or temperature increment/decrement) a user input enables to set the transformation direction manually to
1 for forward phase transformation from austenite to martensite,
, or
-1 for phase transformation from martensite to austenite,
, thus speeding up the computational time.
