The design of the corner joints in furniture structures is very important to firmly support the loaded structure and to sufficiently maintain the durability and stability. Therefore, the strength of the corner joints and the rigidity of the connected panels play a very important role in the structural performance of the assembled furniture. The structural properties can be measured or calculated experimentally or numerically, and compared by representing the applyed forces or bending moments as a function of deformed value. This paper shows the numerical models to determine the strength and stiffness of the 3-types of corner joints for simple designed furniture. Based on the finite element results, the maximum stresses are concentrated on the corner joints designed with MDF panels. And the deformation resistances and maximum applied loads are calculated for furniture corner joints under tensile and compressive moment.

비등방성으로 적층된 복합판 및 쉘구조물에서 온도와 습도의 급격한 변화는 구조물의 강도와 성능을 저하시키는 중요한 원인이 된다. 더욱이 하중에 의한 역학적 변위와 조합될 때에는 좌굴, 대변형 혹은 고응력 상태를 유발하게 된다. 본 연구에서는 이중 퓨리에급수를 이용하여 3차의 전단변형함수로 가정된 평형방정석을 전개하고 폭-두께비, 형상비의 변화 그리고 재료의 성질에 따른 결과에 대하여 고찰하였다.
