PhaseTransformationEigenstrain

Source: models/solid_mechanics/kinematics/PhaseTransformationEigenstrain.py

Define the (cummulative, as opposed to instantaneous) linear isotropic phase transformation (from phase A to phase B) eigenstrain, i.e. \(\boldsymbol{\varepsilon}_\mathrm{PT} = \Delta V f \boldsymbol{I}\), where \(\Delta V\) is the volume fraction change when going from phase A to B, \(f\) is the phase fraction (0 to 1, A to B).
