The second term expresses the released energy in the area around the flaw during cracking, and the third one denotes the additional surface energy of the flaw due to crack. According to the Griffith model ", the flaw will increase its size spontaneously only when a decrease of energy in the sample takes place, that is. 

Emery-Griffiths model (BEG) (Blume et at, 1971). Recently, there have been many theoretical studies of mixed spin Ising systems. These are of interest because they have less translational symmetry than their single-spin counterparts since they consist of two interpenetrating inequivalent sublattices. The latter property is very important to study a certain type of ferrimagnetism, namely molecular-based magnetic materials which are of current interest (Kaneyoshi Nakamura, 1998).

O2 interacts with a single substrate atom (Griffith model) [41] forming a bond between its empty orbitals of the metal surface atom and by forming a partially filled d y or dy metal orbitals to the antibonding n orbitals of O2. 

Let us present our rather simplified scheme of the application of a thermodynamic approach, following the Gibbs-Volmer-Griffith model, to the Hertz problem, described in Section 5.2. Let an indenter leave a hemispherical pit hole with a diameter equal to la and a depth equal to h in the plane of the sample surface (Figure 7.39). 

In the Griffith model (Figure 2), the surface energy vanishes on the crack and rises steeply to the value 2y at the crack tip, inducing a singularity of the stress...
