- Optimization of geometrical sizes of the waveguide of elastic acoustic emission (AE) waves, which is used in the search of hydrogen induced cracking during thermal cycling of structure alloys in a gaseous hydrogen environment, is considered. A waveguide is considered as on acoustic system that has the discrete spectrum of eigenfrequencies. Distribution of temperature field along the waveguide is calculated, decay of elastic AE waves is estimated. Basing on the obtained results the design implementation of the waveguide is carried out.
