Abstract Based on the Zhurkov’s kinetic concept of solids’ fracture a local internal stress estimation method is introduced. Stress field is computed from the time series of acoustic emission intervals between successive signals. For the case of two structurally different materials the time evolution of these stresses is examined. It is shown that temporal changes of these stresses’ accumulation law may serve as a precursor of incoming macroscopic fracture.

The equation proposed earlier has been derived from a new kinetic concept. It is shown to be a reasonable approximation of this new consideration. The equation is also shown to be mathematically consistent with the general fact that when the thermomolecular pressure difference is plotted against the normally measured pressure, a single maximum is obtained. The curves calculated from this equation are shown to agree closely with those from the Weber equation using van Itterbeek and de Grande's data. The practical use of the equation is discussed.

The main processes occurring during vacancy generation in aluminum in the presence of hydrogen are described on the base of ab initio methods using the meta-functional SCAN. It was shown that hydrogen reduces the vacancy generation energy from 2.8 eV to 0.8 eV. In this case, eight hydrogen atoms located in the tetrahedral voids of the lattice around one aluminum atom make it much easier for it to move to the interstitial site. In accordance with the kinetic concept of embrittlement the dependence of the activation energy of hydrogen embrittlement of aluminum is calculated on the concentration of hydrogen and temperature. It is shown that hydrogen reduces the time of aluminum embrittlement only if its concentration in aluminum is more than critical one (~3⋅〖10〗^(-4) at T=293 K).
