ABSTRACT: The design of wooden furniture is almost never the subject for mathematical considerations.
Instead, the designer rests on experimental experience and constructs for example chairs with dimensions of
structural members based on tradition reasons. By the much more common use of computers it is nowadays
possible to use modern finite element method analysis in various stages of the design process. Furthermore use of
FEM analysis in furniture design has improved quality and reduced the need for creating and testing a physical
prototype in design. This paper investigated the static and fatigue behaviors of mortise and tenon joined armchair
frames constructed of Beech (Fagus Orientalis L.) wood material. The finite element method (FEM) was utilized
for analyzing the armchair construction by ANSYS Workbench software. The results show that there are close
convergence between experimental study and FEM (static and fatigue) analysis results. The consistency level
between the static test result and the static FEM analysis obtained at 5 mm mesh sizes was 97.74%. Furthermore,
the consistency level between the fatigue test result and the fatigue FEM analysis obtained at same mesh size was
87.5%. As a result, FEM gives reasonable estimates of the overall strength performances of the armchair
