1.	Martensite fraction rate:

2.	Martensite fraction:

3.	Mechanical behavior:

4.	The temperature is computed assuming the adiabatic condition (by default the condition is isothermal with Cp = 1030):

where, Eint is the internal energy of the element.

5.	B must satisfy this condition:

(1 + B)/B < p
