Introduction The physical and mechanical properties of wood depend on numerous factors. (Janiak et al. (2023); Gong et al. (2019); Matviiuk et al. (2025); Sinha et al. (2012); Roshchuk et al. (2024); Moya and Bano (2017)). These properties can be improved in various ways (Petric (2013); Homon et al. (2024); Lamichhane et al. (2025); Mykhailovskyi et al. (2025); Abolore et al. (2025); Bula and Pelekh (2023)). Wood can work under different types of loads (Zakic (1974); Homon et al. (2024); Patton-Mallory and Cramer (1987);Pavluk et al. (2024); Thelanderson and Larsen (2003); Gomon et al. (2022)). It is used as one of the main materials for the construction of buildings and structures. (Ivaniuk et al. (2025); Hua et al. (2025); Sobczak-Piastka et al. (2023); Andor and Bellovics (2020); Gomon et al. (2024); Kohler et al. (2007)). One of the main advantages of wood is its ease of processing, which allows flexibility in manufacturing various products and structures. (Aleksiievets et al. (2024); Shams Huq et al. (2025); Homon Abstract The mechanical properties of composite prisms fabricated from wood veneer under axial compression along the grain by a single short-term load were evaluated in article based on an experimental study. The ultimate short-term strength, relative critical and residual strains in the pre-critical and post-critical stages of material behavior were evaluated. The failure mechanism exhibited a brittle – plastic character, involving local macrocracks, interlayer delamination of veneer sheets, and crushing of wood fibers. These findings highlight the critical role of the multilayer architecture and adhesive quality in ensuring the structural integrity of the composite material. The results of the research showed that the industrial method of manufacturing prisms with a controlled veneer layer thickness and adherence to the technological regime, ensures stable physical and mechanical properties and high reproducibility of experimental outcomes. The obtained data can be used for the design of structural elements made from wood veneer, for evaluating their strength and deformation characteristics, as well as for further investigations into the effects of multilayer architecture and interlayer adhesion on the mechanical behavior of composite materials.
