Abstract
The paper presents results of the photoacoustic visualization of fields of residual stress
in ceramic material based on silicon nitride. Theoretical analysis yields that the main contribution
to the change of photoacoustic (PA) response value is made by nonlinearity of elastic properties
of the medium.
