Elasto-Plastic Analysis of Mortise-Tenon Joint With Dowel Subjected to Cyclic Loading

Abstract

We propose an incremental analysis method with a model considering compressive strain inclined to the grain and friction in a mortise-tenon joint with dowel to examine the hysteresis characteristics of the joint subjected to cyclic loading. We introduced a concept of apparent shear stiffness based on the Coulomb's friction into constitutive law. The analysis method can evaluate cyclic hysteresis characteristics of the joint with constitutive law based on material tests. We performed a bending test of a T-type specimen composed with a beam and a column, and confirmed validity of the proposed analysis method.

Effect of selected factors on stiffness of dowel joints

“…The elastic stiffness of a joint can be influenced by several factors (Masui et al 2013). In this article, the authors focused on several important factors that affect the elastic stiffness of dowel joints, such as the type of load, joint thickness, type of adhesive used, annual ring deflection, and finally the type of bonded wood or composite material.…”
