Abstract
Bu çalışmada basit eğilme altında eğri eksenli dar dikdörtgen kesitli bir kirişin elastikplastik analitik çözümü türetilmektedir. Küçük deformasyonlar ve düzlem şekil değiştirme durumu varsayılmıştır. Kirişin plastik davranışı Tresca akma kriteri ve ilgili akma kuralı yardımıyla lineer pekleşen malzeme için formule edilmistir. Bu koşullar altında, kirişin elastik-plastik davranışı tarif eden tek bir diferansiyel denklem elde edilmiştir. Elastik-plastik bölge denklemleri sözkonusu diferansiyel denklemin analitik çözümlenmesiyle çıkarılmıştır
In this study analytical solution of elastic-plastic narrow rectangular cross sectional curved beam subjected to pure bending is derived. Infinitesimal deformations and plane strain conditions are assumed. Plastic behaviour of the beam is formulated with Tresca’s yield criterion and its associated flow rule for linearly strain hardening material. Under these conditions one single differantial equation describing the elastic-plastic behaviour of the beam is obtained. The field equations for the elastic and plastic regions are then determined by the analytical solution of the governing equation.
