The Measurement of Compressible Elasticity Modulus and Poisson Ratio of Ziziphus Montana Wood

摘要：

　　Timber is a typical orthotropic material, of which the accurate measurement of elasticity modulus and Poisson ratio is important.In this article, the test samples are manufactured according to GB 1943-1991 and 1935-1991.An electronic testing machine is employed to add longitudinal load on samples and the longitudinal and transverse strains are measured via Wheatstone bridge.Then, the compressible elasticity modulus and Poisson ratio of Ziziphus montana wood in three directions is obtained.The results show that the elasticity modulus measured is of similar magnitude to those with similar dry density and of great importance to finite element calculation.
