摘要: In this study, in-plane stability analysis of non-uniform cross-sectioned thin curved beams under uniformly distributed dynamic loads is investigated by using the Finite Element Method. The first and second unstable regions are examined for stability. In-plane vibration buckling also studied. Two different finite element models, representing variations cross-section, developed simple strain functions in analysis. results obtained from study compared with other investigators existing literature fundamental natural frequency critical load. effects opening angle, static load parameters on shown graphics.
