Stability of cabinet furniture backing boards

Summary Rigidity of cabinet furniture and load carrying ability of different classes of surface constructions depend on stability of sheets used as sheathing or back walls of these structures. The process of loss of stability by large sheets of wood boards (fiber and plywood boards) has not been sufficiently studied. The aim of this study was to carry out laboratory investigations on the phenomenon of the loss of stability by fiber and pine plywood boards used as back walls differently mounted to bodies of cabinet furniture. Experimental results were verified by theoretical calculations which showed satisfactory consistency. They also confirmed possibility of checking dimensions of these boards in finished constructions.
