Detection and estimation of Hylotrupes bajulus L. wood damages by ultrasonics

IRG/WP 2350

G Prieto

To evaluate the validity of the ultrasonic application in the detection and evaluation of wood damages produced by Hylotrupes bajulus L. larvae, some laboratory tests were made with small wood samples. The pulse through transmission method was used. The transit time of ultrasonic pulses in transversal sections, radial and tangential, of the samples was measured. The increment of the transit time of ultrasonic pulses with respect to clear wood gave to this method the way to estimate the damage grade.
