Elasticity modulus of cabinet furniture joints

• Elaboration of elasticity moduli of furniture L-type joints.
• Calculation of elasticity moduli of furniture joints.
• Numerical calculation of furniture stiffness for different joints.
• Experimental verification of the correctness of the elasticity modulus of joints.

Designing of furniture stiffness with the assistance of computer aided engineering (CAE) requires determination of joint stiffness coefficients or realistic modelling of elastic bodies which remain in contact with one another. The objective of this study was to determine elasticity moduli of furniture L-type joints, numerical calculation of furniture stiffness with joints which were assigned elasticity moduli as well as verification of the results of these calculations employing, for this purpose, experimental investigations. The correctness of the elaborated model of joint elasticity modulus was verified positively by empirical studies. The developed model makes it possible to conduct an objective comparison of joint stiffness and, on this basis, to select the most advantageous solutions. The application of joint elasticity moduli simplifies numerical analysis of cabinet furniture construction.
