Section modulus of corner joints in furniture frames as engineering design criteria for their efficient construction

► The best construction of corner angle joints can be determined by: the ratio of the section modulus Wp of the joint to the section modulus We of the joint element. ► As the value of the ratio Wp/We approaches one the optimum solution of the joint is determined based on its ability to transmit mechanical loads. ► The results could increase the development of the full strength of the material, reduce the consumption of wood material and contribute to technological improvements.
