FONKSİYONEL DERECELENDİRİLMİŞ KAPLAMALARDA SÜRTÜNMELİ RİJİT ZIMBA ETKİSİYLE OLUŞAN YÜZEYALTI TEMAS GERİLMELERİ
Abstract
Bu çalışmada, fonksiyonel derecelendirilmiş malzeme (FDM)’den yapılan bir kaplamada yüzey altında, temasyüzeyindeki düzgün profilli sürtünmeli rijit zımba etkisiyle oluşan, gerilme dağılımlarını hesaplamak için tekilintegral denklemlerine dayalı bir yöntem geliştirilmiştir. Düzlem elastisite durumu ele alınmış ve Poissonoranının, homojen gövde ve FDM kaplama için aynı olduğu kabul edilmiştir. Problem, bir tekil integraldenklemine indirgenmiş ve bu denklem bir açılım – sıralama tekniği kullanılarak sayısal olarak çözülmüştür.Tekil integral denkleminin çözümünde kullanılan seriler Jacobi polinomları kullanılarak ifade edilmiştir. Zımbagenişliği, zımba konumu, sürtünme katsayısı ve malzeme parametrelerinin, kaplama derinliği boyunca oluşangerilme dağılımlarına etkileri incelenmiştir.
