Study on Shear Modulus of Elasticity of Plywood by Vibration Method
A surface wave propagation method was proposed to measure the dynamic shear moduli of plywood for the first time. The testing results of the dynamic shear moduli for plywood measured both by flexural vibration method and surface wave propagation method were different. According to the theoretic analysis, the surface wave propagation method was more suitable for nondestructive testing of dynamic shear moduli of plywood since it could solve the problem especially for measurement of dynamic shear moduli of plywood with 45° grain angle.
