Element for drift pins is modeled by isotropic elasto-plastic material, element for glulam is modeled by orthotropic elastic material and element for interspace between drift pin surface and glulam hole surface is modeled by virtual material with very small Young's modulus. We show the numerical examples of the analysis and discuss about them.
