During the last few decades, mathematical and computational modeling of tumor growth has received a lot of attention from the scientific community. However, as noted in [14], there are no established first principle theories in cell-tissue modeling, and this seems to be the case even for today...
Assuming that the structural damage is in the form of a change in the structural stiffness, the stiffness value at position i of the damaged structure can then be expressed as: Kid = θiKi (2) where Ki is the stiffness of the i-th element in the reference state (undamaged, baseline ...
