1. the method for numerical simulation of an anisotropy of wood plastic yielding constitutive model, it is characterised in that:

  • comprise the steps,S1;

    timber is assumed to orthotropic material, builds the constitutive model of timber, and is reduced to bilinear model;

    S2;

    use the accurate yield criterion as timber of Tsai-Wu intensity;

    S3;

    postulate with Drucker and unanimity rule is to describe timber Plastic Flow yield surface.
