Finite element modelling of anisotropic elasto-plastic timber composite beams with openings

Abstract In this paper, constitutive equations to model anisotropic elasto-plastic timber composite beams with openings were formulated and implemented into the finite element (FE) package ABAQUS, via a user-defined subroutine. The Tsai–Hill criterion was applied to judge failure of Oriented Strand Board (OSB) and timber in tension. Both OSB and timber in tension were modelled as linear orthotropic elastic materials, and in compression as orthotropic elasto-plastic materials. Good correlation has been obtained between the experimental results and the FE simulations. The user subroutine was used to check and remove critical elements, through which crack growth was simulated. In addition, interactions between two openings were modelled, which gave the corresponding critical distance.
