In- plane dynamic stability analysis of laminated curved beams

In this study, the effects of variations of subtended angle, orientation angle and curvature of a laminated composite arc, having an in-plane curvature, on the natural frequencies, static and dynamic stability have been investigated by using the Finite Element Method. Sabir and Ashwell?s displacement functions have been used to develop a finite element model to employ in this study. In-plane vibration and in-plane buckling analyses are also studied. In addition, the results obtained from this study are compared with the results obtained from Ansys for the fundamental natural frequency and critical buckling load. The effects of variations of subtended angle, orientation angle and curvature of curved beam and static and dynamic load parameters on the stability regions are shown in graphics. Moreover, analysis of natural frequencies, buckling and dynamic stability for curved composite beams are also compared.
