Interaction of waves and fields such as in photoelasticity or acoustoelasticity shows explicitly how new wave structures may be formed and how informative they are (see overview by Engelbrecht [5]).

(b) Photographs experimentally taken utilizing dynamic photoelasticity in conjunction with high-speed cinematography show the time-dependent isochromatic fringe patterns (distributions of [[tau].sub.max]) generated near a free surface by supershear dip-slip rupture (V [congruent to] 1.73-1.98 [V.sub.s]) on a model fault plane (initially welded interface) between two identical transparent, birefringent linear elastic polycarbonate plates.

Among the topics are electrical strain gages, optical methods using the interference and diffraction of light, photoelasticity, MoirA[c] contouring applications, and holographic interferometry.
Unlike other methods (the method of strain measurement, the method of photoelasticity, etc.), the magnetic diagnostics by the coercive force reacts to the restructuring occurring residual stresses, mounting tension.

In order to determine the latter, this paper presents a comparative study carried out using the finite element method and the photoelasticity technique of the stress state in the tightened plates of a screw assembly.
Photoelasticity was used as a qualitative method but it presents too many difficulties in the quantitative analysis of stress, and also this method doesn't define which type of stress is generated.
