| description | Abstract Composite elements made of wood reinforced by adhesively inter-layered steel lamina can be employed as structural elements in building engineering, thanks to their favorable ratios of strength and stiffness to mass and their ductility. The mechanical response of such composite, under loading, can be predicted by employing a Finite Element Method with a proper model of each material. In this work, the Finite Element Method model is formulated within the theories of Continuum Mechanics and irreversible thermodynamics of deformation, finite strains hypothesis, and kinematics of large displacements. For the wood material constituent an orthotropic elastic–plastic-damage constitutive law is adopted, to address the effects of irreversible strains, formulated by a multi-surface yield, both for plasticity and damage, where each yield surface operates disjointedly each other, at the level of stress–strain component. The validity of the proposed model and its computational technique is revealed by analyzing the stress–strain path until the failure of a composite element. Thus, the numerical results are compared with the experimental data obtained in a tension test of that composite element. The proposed model adequately represents the mechanical behavior of the composite. |
