The growing demand for sustainable practices in the construction industry has driven the use of renewable materials, such as wood, due to its structural properties, lightness, strength, durability, and carbon sequestration capacity. However, the use of wood faces challenges, particularly due to the variability of its characteristics and the need for more effective, accessible, and rapid evaluation methods. This study investigated the correlation between the longitudinal modulus of elasticity obtained by static bending (MOE_e) and the dynamic modulus of elasticity (MOE_tv) determined by transverse vibration, using smartphones as a measurement tool. A total of 215 samples from 10 different wood species were analyzed using static bending and transverse vibration tests. The results showed a significant correlation between MOE_tv and MOE_e (0,49 ≤ R² ≤ 0,98), validating the effectiveness of the transverse vibration method using smartphones. The technique proved to be an efficient approach for predicting the modulus of elasticity, offering an economical and accessible alternative for mechanical characterization, contributing to sustainable practices in the construction industry and proposing an innovative and precise method for this material. Keywords: elasticity modulus; vibration; wood; smartphone.
