The variables dynamic modulus of elasticity (MOEd) as well as the modulus of elasticity (MOEe) and the modulus of rupture (MOR) in static flexion were evaluated in accordance with the ASTM D-143-94-2000 and ASTM D-5536-94 -2004 method primary method and secondary method in order to estimate the degree of prediction of MOEe and MOE through MOEd For the determination of MOEd, the Microsecond timer (23KH) was used in three positions of the transverse section of the specimen and the Ultrasonic timer (45 kh) in the tangential and radial faces. In both cases, no statistical differences were found in both the primary and secondary methods. The behavior in the three longitudinal levels in the MOEd with Microsecond and Ultrasonic timer equipment is similar to the obtained with the MOEe, both in the primary and secondary method and the linear regression that best estimates the MOEe is: MOEd = 32220 + 0. 7915 MOEd microsecond, of the primary method.
