Summary
Acoustic emission (AE) generated in pine wood samples upon bending across the grain under simultaneous moistening of the tension zone, was measured. The aim of the study was to determine the effect of external tension load on AE generated during asymmetrical moistening of dry wood samples in water. The cumulative counts of AE signals recorded during simultaneous moistening of the tension zone of sample were proportional to the intensity of the mechano-sorptive strain. AE starts when the mechano-sorptive strain in the tension zone (εT) reaches a value close to 0.8%.
