摘要: 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 judge failure of Oriented Strand Board (OSB) in tension. Both OSB tension modelled as linear orthotropic elastic materials, compression materials. Good correlation has been obtained between experimental results FE simulations. user subroutine used check remove critical elements, through which crack growth simulated. addition, interactions two modelled, gave corresponding distance.
