Kerf-kesme tekniği uygulanmış ahşapların eğilme davranışının deneysel analizi

Öz

Tarih boyunca ekolojik faydaları ve hafifliği ile bilinen ahşap, doğru tekniklerle işlendiğinde esneklik kabiliyetini arttırabilmektedir. Bu esneklik, farklı mimari ürün ve mobilyaların üretilmesine ilham yaratmıştır. Bu çalışmanın amacı, kerf kesim tekniği ile esneklik kazandırılmış farklı doğal ahşap numunelerinin esneklik düzeylerini ve bu düzeylerde taşıyabildikleri azami yükü incelemektir. Literatürde, kerf kesim tekniklerinin farklı doğal ve endüstriyel ahşap ürünlerini ne kadar esnekleştirebildiğine dair çalışmalar olsa da kerf tekniğinin sağladığı esneklik ile taşıma kapasitesi arasındaki ilişki incelenmemiştir. Çalışma bu açıdan özgündür. Makalede öncelikle farklı ağaç türlerinin genel fiziksel özellikleri ve eğilme kapasiteleri incelenmiştir. Sonrasında ise iki etaplı bir deneysel çalışma ortaya konmuştur. Bu deneysel çalışmanın ilk aşamasında, farklı kerf kesim tekniklerinin ahşabın esnekliğine etkisi, ikinci aşamada ise üç farklı ahşap tipinin esneklik ve taşıma kapasiteleri araştırılmıştır. Sonuçlara göre, dişbudağın en fazla esnekliğe sahip olduğu, cevizin ise yük taşıma kapasitesi olarak dişbudaktan daha yüksek mukavemet gösterdiği, dolayısıyla daha fazla mukavemet gerektiren tasarımlar için uygun olduğu belirlenmiştir.

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

Öz

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.
