In this study, the effects of variations of subtended angle and orientation angle of a
laminated curved beam having an in-plane curvature, on the dynamic stability have been
investigated by using the Finite Element Method. In addition, the results obtained from this
study are compared with the results obtained from ANSYS program for the fundamental
natural frequency and critical buckling load. The effects of variations of subtended angle,
orientation angle, static and dynamic load parameters on the stability regions are shown in
graphics.

TABAKALI EĞRİ ÇUBUKLARIN DİNAMİK KARARLILIK ANALİZİ

Öz

Bu çalışmada, düzlem içerisinde belirli bir eğriliğe sahip tabakalı kompozit dairesel bir yay parçasının, merkez açısının ve tabakalardaki fiber açılarının değişiminin dinamik kararlılığa etkileri sonlu elemanlar metodu kullanılarak araştırılmıştır. Ayrıca birinci doğal frekans ve burkulma yükü değerleri ANSYS programından elde edilen sonuçlarla karşılaştırılmış ve eğri çubuğun merkez açısının, fiber açılarının, statik ve dinamik yük parametresinin kararlılık bölgeleri üzerindeki etkileri grafikler ile gösterilmiştir

Anahtar Kelimeler
