Abstract
Non-Destructive Testing (NDT) is a method proposed in the material studies to determine the physical and mechanical properties of a material without altering its end-use capabilities. This paper reports the investigation made the bending strength properties of timber beams using ultrasonic wave non-destructive test method and static destructive test. Timber beams from eight selected Malaysian timber of different strength grouping; Resak (SG4), Kapur (SG4), Merpauh (SG4), Bintangor (SG5), White Meranti (SG5), Jelutong (SG6), Sesendok (SG7) and Kelampayan (SG7) were used. The results from static and non destructive tests were statistically correlated and compared taking into account the density of the timber. The mean value for the modulus of elasticity established from the NDT tests were found to be higher than the corresponding value established from static tests.
