Elastic constants of Chilean Pinus radiata using ultrasound

Elastic constants of Pinus radiata were determined using ultrasound technique. In parallel, typical compression mechanical testing was carried out to compare the effectiveness nondestructive test The longitudinal elastic constant values similar (ultrasound technique 12,8 % higher than testing), showing that is a reliable and valid tool. for radial tangential moduli obtained by versus showed more differences. This may be due difficulty in obtaining adequate samples testing. symmetry shear modulus revealed (Gij = Gji). Poisson’s ratios not comparable either method; however, consistent with existing literature species. Additionally, anisotropy analyzed wood demonstrated through velocity propagation material. It thus possible obtain twelve engineering characterize behavior means proposed
