Book Description
A cantilever-beam vibration-testing apparatus has been developed to provide a means of dynamic and non- destructive evaluation of modulus of elasticity for small samples of wood or wood-composite material. The apparatus applies a known displacement to a cantilever beam and then releases the beam into its natural first-mode vibration and records displacement as a function of time. That frequency and amplitude attenuation is then used to calculate the dynamic material properties of the cantilever beam. The dynamic testing is quick and calculates the dynamic modulus and loss-tangent damping coefficient.
