Experimental and theoretical analysis of impact of shape selected type of self-locking joints on their mechanical properties

Popis výsledku v původním jazyce

The main objective of this work is to determine the influence of the shape and dimensions of the tenon and mortise of self-locking frame joints on their mechanical properties. We studied three groups of joints. The basic joint has the tenon with a shaped head and straight arms. The other two joints were created by modifying the dimensions and shapes of arms of the joint. All joints were made from plywood with thickness of 18 mm; it is material which is suitable for production of these types of joints. The test specimens were loaded under the pressure caused by bending in the angular plane. The load carrying capacity and stiffness of the joint were evaluated. It has been found that the stiffness and deformation of the joint are influenced by the shape and dimensions of the joint. This statement is supplemented by numerical models created using the finite element method (FEM) for the purpose to optimise the joints. The results show that creating additional pins and changing dimension of the tenon can improve mechanical properties of the self-locking joint.
