Abstract: Wood-plastic composites (WPCs), commonly used in residential decks and railings, exhibit mechanical behavior that is bimodal, anisotropic, and nonlinear viscoelastic. They exhibit different stress-strain responses to tension ...

Abstract: The main goal of the present paper is to demonstrate the value of design optimization beyond its use for structural shape determination in the realm of the constitutive characterization of ...

Abstract: A thin, solid, circular wood disk, cut from the transverse plane of a tree stem, can be modeled as a cylindrically orthotropic elastic material. It is known that a stress singularity can occur at the center of a cylindrically ...

Abstract: Application of orthotropic constitutive models to lumber with cross grain requires transformation of coordinates when material axes are not aligned with board axes. This paper presents a procedure to construct the coordinate ...
