Abstract: Stress at first acoustic emission event-count, as well as cumulative event-count at 80 percent of mean failure stress and cumulative event-count at 80 percent of mean proportional limit stress were separately regressed on strengths of finger joints from Obeche (Thiplocblmn sclerarylon). Makore (Tleghemeia heckelii) and Moabi (Baillondla toaispernw). Me regression suggested that all the three acoustic emission properties could be used to non-destructively predict the ultimate tensile and bending strengths of finger joint from the three hardwoods . However, stress at first event-count seemed most suitable for predicting ultimate tensile strength of finger joint from the three species, whilst cumulative event-count at 80 percent of mean failure stress seemed best for modulus of rupture. Correlation coefficients obtained for the prediction models developed were, generally, good and statistically significant (a 0.05).
