A new method for the determination of the proportion of wood failure area on the glue bond

Ovaj rad prikazuje postojeće standardne metode za mjerenje i određivanje udjela lomnih površina kroz drvo, nedostatke njihove primjene te usporedbu standardnih metoda s novom metodom. Novom metodom za određivanje udjela loma kroz drvo uklanjaju se nedostaci postojećih metoda odnosno subjektivni utjecaji ispitivača i povećava se preciznost mjerenja. Metoda se temelji na fotografiranju lomnih površina koje se zatim obrađuju i analiziraju računalom. Rezultati pokazuju da je ova metoda objektivnija i točnija od normiranih metoda.This paper presents the existing standard methods of measurement and determination of the proportion of glued wood failure surface, disadvantages of their use and comparison of standard methods with the new one. The new test method for the determination of the proportion of failure surface eliminates the flaws of standard methods and decreases the subjective effects of the examiner, and at the same time increases the precision of measurement. The method is based on images made with digital camera, which are then processed and analysed by computer. The results show that this method is more objective and more accurate than standard methods
