The fuzzy characteristic of adhesive quality is researched when multi-layered structure of the solid rocket motor is inspected in angle beam echo method by focused transducer.Fuzzy subordinate function model of the adhesive quality is set up based on the researches in theory and experiment.Fuzzy pattern recognition on the adhesive quality of the each(More)
In inspecting steel-rubber multi-layered structure, shielding of steel layer and intense attenuation of rubber layer result in ultrasonic echo from the interfaces of the deep layers being very weak. In order to overcome the difficulty, the double mode testing method is put forward. This method synthesizes the characteristics of transverse wave and Lamb wave(More)
