Odun teknik olarak anizotropik
bir malzemedir fakat genellikle transvers izotrop olarak modellenir. Ayrıca
silindirik yapısı nedeni ile polar ortotropik bir yapısı vardır. Odunun Sonlu
Elemanlar Analizi (SEA) için doğrusal elastik bölge, plastiklik, transvers
izotropik plastiklik, Hill akma kıstası gibi birçok teori kullanılabilmektedir.
Ahşap yapıların güvenli bir şekilde işlevlerini yerine getirebilmeleri için
bileşenlerinin ve sistemin tümünün elastik bölge sınırları içerisinde
davranması gereklidir. Bu çalışmada farklı enine kesit ölçülerindeki ön ve arka
ayaklı kayın (Fagus orientalis L.) sandalye
çerçevelerinin SE Analizi CATIA yazılımı ile gerçekleştirilmiştir. Elde edilen
sonuçlar, enine kesit değerinin yük taşıma ve yükü tüm yapıya iletmede önemli
olduğu ve bağlantı noktalarındaki gerilimi etkilediğini göstermiştir.
