Experimental analysis of the bending behavior of woods with kerf-cutting technique

Throughout history, wood has been recognized for its ecological benefits and lightness. Its flexibility can be significantly enhanced when processed with proper techniques, inspiring various architectural products and furniture. This study aims to investigate the bending capacity of different natural wood samples made flexible using the kerf-cutting technique and the maximum load they can bear at their maximum bending capacity. Although there are studies on how kerf-cutting techniques can increase the flexibility of various wood products, the relationship between the bending capacity provided by the kerf technique and load-bearing capacity has not been examined, making this study original. The paper first examines the general physical properties and bending capacities of different wood types. Then, a two-stage experimental study is presented. The first step discusses the effects of different kerf-cutting techniques on wood flexibility. In the second step, the bending and load-bearing capacities of three different types of wood are investigated. Results indicate that ash has the highest flexibility, while walnut demonstrates greater load-bearing strength than ash, making it suitable for designs requiring higher strength.
