Study of the stress-strain state in corner joints and box-type furniture using Finite Element Analysis (FEA)

This article explores the possibility of analysing the stress and strain state in corner joints, typically found in furniture box-type structures, by using Finite Element Analysis (FEA). Based upon experimental research, a new model is proposed for the structural analysis of corner joints, where they are considered as a macroscopic and interactive part of box-type furniture. The fixing components, which connect the elements of physical joints, are replaced by elastic finite elements, the properties of which are determined experimentally. As a result, the stress concentration areas in the model are developed as in the physical joints, and the stress-strain state in corner joints can be accurately predicted. Finally, the deflection of cabinet furniture is predicted and the results obtained are compared to some similar published results.
