Dynamic and Static Testing of Poisson's Ratio of Oriented Strand Board

【Objective】This study was carried out to discuss the applicability of cantilever plate first-order bending mode method（dynamic method） and cantilever plate static bending method（static method） to test the longitudinal and horizontal Poisson's ratio of oriented strand board（OSB） .【Method】The dynamic and static stress and strain analysis of OSB cantilever plates were carried out using ANSYS modal program block and static bending program block,and the OSB longitudinal and horizontal cantilevers with an aspect ratio of 3 to 6 and a width to thickness ratio of 4 to 10 were calculated.The stress and strain of the plate,the position where the horizontal stress in the cantilever plate being equal to zero was determined,that is,the position of the strain gauges for dynamic and static tests of OSB longitudinal Poisson's ratio and horizontal Poisson's ratio,and the binary regression analysis was applied to express it as dependent on the relationships between the width to length ratio and the thickness to width ratio of
