摘要：This study aims to investigate the relationship between the anatomical features and the mechanical behavior of poplar wood and reveal the deformation mechanism of hardwood under transverse compression. We conducted a transverse compression test of the poplar wood, a typical diffuse porous wood, under uniaxial, laterally restrained, and circumferentially restrained conditions. Subsequently, a finite element model was developed based on SEM images of poplar wood. Finally, the deformation mechanism of the wood was analyzed based on the test and modeling results. This study is helpful for understanding the mechanism of poplar wood under transverse compression and the development of constitutive models based on its mechanism.
