STUDY OF THE EFFECT OF MOISTURE-CONTENT O N BRITTLE SOLID PRODUCTS BYACOUSTICAL EMISSION ANALYSIS

The impact of moisture content on various properties of material was s tudied using acoustical emission. The idea consists of the analysis of sound emission which accompanies the rupture of the product. This met hod is characterised by its ease of adaptation and application. The pr esent paper shows the effect of moisture content on several mechanical properties of pasta through the evolution of their behaviour and the analysis of acoustical signal emitted during rupture. The results show ed a similar trend of different acoustical and mechanical parameters v s humidity. It is therefore possible to calculate correlations between these two sets of determinations.
