Acoustic emission in fracture mechanics of wood

Jan Raczkowski, Waldemar Moliński, Zbiqniew Ranachowski
Acoustic emission (AE) in wood can appear as a result of mechanical stresses caused by mechanical, external loading or wood-internal sorptive stresses. Since the AE phenomena depending on both those reasons are of different nature, therefore the AE generated under mechanical and sorptive loading will be described separately in this paper.
