Abstract: The present invention discloses a method for evaluating the sound speed end dynamic modulus of elasticity of wood by non-destructive stress wave testing, wherein a timber specimen of long post is placed steadily on a sensor near the center with friction, acting on the interfaces of the sensor and the timber specimen, which resists the timber specimen from moving. Pounding one end of the timber specimen with a striking instrument sends a compression pulse stress wave down the post toward the other end, thereby generating a tension pulse wave back along the post till friction exponentially dissipates the energy of the stress waves. The changing signals of friction received by a receiver support the analyzer to measure longitudinal fundamental frequency of timber specimen; therefore, sound speed and dynamic modulus of elasticity are then calculated.
