The aim of this work was to accurately measure the Poisson′ s ratio and Young′ s modulus of gray manila board and ivory board. The combination of digital image correlation method (DICM) and tensile test was used in this paper. The Poisson′ s ratio was measured by analyzing the images of the gray manila board and ivory board specimens before and after tensile deformation. And the Young′ s modulus was measured by analyzing the force-displacement curves of gray manila board and ivory board. The Poisson′ s ratio for gray manila board with ration of 300 and 400 g/m2 was 0.281 and 0.245, respectively, and the Young′ s modulus was 154.47 and 226.06 MPa, respectively. The Poisson′ s ratio for ivory board with ration of 300 and 400 g/m2 was 0.312 and 0.276, respectively, and the Young′ s modulus was 209.09 and 297.79 MPa, respectively. The higher ration corresponded to the higher Young′ s modulus and the lower Poisson′ s ratio for the same category of board. In the case of the same ration, the Young′ s modulus and Poisson′ s ratio of ivory board were higher than those of the gray manila board.
