This work is devoted to studying the influence of angular momentum variation in
an elementary volume and cross flux on its sides on some equations of continuum mechanics.
The self- diffusion effect is investigated for fluctuations of shock waves for the Mach number
M≈1. As another example, a beam and a plate are considered.
Keywords: angular momentum; conservation laws; nonsymmetrical stress tensor; Boltzmann equation; Chapman-Enskog method; the Navie-Stokes equation
