Abstract:

Three elastic parameters of masson pine were measured by using resistance strain gages.The results of the experiments show that(1) EL parallel to grain in compression can be measured by strain gages fixed only on radial surface (LR-plane). (2)There is a good agreement between EL and air-dry density. (3) A good estimate of the compliance can be obtained from the derived equations.
