Detection of defects in joints using the variations in dynamic shear modulus and Correlation Coefficient factor in Beech Wood

In this study, detect of damage in scarf joint and finger joint using the variations in dynamic shear modulus values and Correlation Coefficient factor of the beech wood specimens was investigated. Numbers of 42 Samples were selected according to ISO 3129 international standard. The Scarf and finger...
