Numerical analysis of compressive performance for the Korean traditional joints

A full three-dimensional finite element model was created using continuum solid elements in ANSYS to gain more insight into the mechanical behavior of the Korean traditional joints. Orthotropic properties were characterized and non-linear analysis was also conducted for the reflection of wood property. For the joint character, not simple joint analysis but specially contact-target analysis was considered to reflect the situation between mortise and tenon. The numerical value is similar to the average value of actual compressive strength tests. Also, the types of stress concentration on the joint were similar to actual failure types. Therefore, we could verify the validity of finite element model that we have developed on the traditional joints. So, the numerical analysis model developed from this study may be utilized for the analysis and design of the various traditional joints.
