In-plane mechanical properties of birch plywood

There is an increasing demand for engineered wood products in modern structures. Birch plywood promising structural applications, due to the combined advantages of its superior mechanical properties and cross lamination configuration. However, off-axis birch have not been thoroughly investigated. The aim this paper establish a comprehensive experimental dataset that could serve as input analytical or numerical models design under various load conditions. Specifically, tensile, compressive shear tests were conducted five different angles face grain, i.e., from 0° (parallel) 90° (perpendicular) with interval 22.5°. stress–strain relationships, failure modes, strength elastic are highly dependent on load-to-face-grain angle. also predicted by empirical models. Parametric analyses performed study influence interaction coefficient F12 Tsai-Wu criterion Poisson’s ratio ?xy transformation model modulus respectively. Lastly, possibilities predicting on-axis based uniaxial discussed paper.
