Reliable location of Acoustic Emission (AE) sources is one of the most important inverse problems in non-destructive testing (NDT) and structural health monitoring (SHM) of engineering structures. Standard AE source location procedures often fail in more complicated structures with wave dispersion, velocity or geometry changes, etc. Localization of continuous AE signals generated by leakage,...
Optimal sensor configuration in cases of complex structure shapes is one of the crucial steps and a premise for precise acoustic emission (AE) source location estimate. Such task leads to numerical analysis of relations between the signal arrival chronology and the coordinates of emission source. Local problems of AE source positions ambiguities in case of continuous 2D body can be...
The aim of this talk is to present round robin tests performed in an aluminum sample presenting a calibrated slit and a hole with the same size. Nonlinear acoustics and vibration has become increasingly important during the last forty years due to the increase of higher sensitivity of electronic instrumentation and its associate signal processing algorithms. The nonlinearity of materials...
Acoustic emission (AE) method belongs to non-destructive methods in defectoscopy. By means of AE we are able to reveal the damage in materials or construction before fatal destruction of the construction (that is very useful for example in case of bridges or nuclear reactors). Classification of AE consists of two main parts. First we have to find some significant parameters of measured signals...
