Abstract
The paper presents results of the photoacoustic visualization of field s of residual stress in ceramic material based on silicon nitride. The oretical analysis yields that the main contribution to the change of p hotoacoustic (PA) response value is made by nonlinearity of elastic pr operties of the medium.
