Dynamic response of the curved beam by using mesh based method and meshless method

This paper presents two different numerical approaches for analysis of the curved beam structures with constant curvature in the plane under the dynamic loading. The first numerical model is based on the Finite Element Method (FEM) that applies exact curved beam element with six degrees of freedom. The second numerical model is based on the Fup Collocation Method (FCM) which allows the application of the strong formulation and uses the Fup basis functions. By introducing inertial forces in the system of three differential equilibrium equations of the second order for the static analysis, the differential formulation for obtaining dynamic response of the curved beam is obtained. The results obtained by using these two numerical methods are compared.
