Dynamic Stability Analysis of the Laminated Composite Curved Frame Structures

In this study, the dynamic stability analysis of laminated composite single-bay and two-bay curved frame structures has been investigated. For purpose, a computer code is written in MATLAB to evaluate natural frequency values, critical buckling load, first unstable regions frames. The effects radii curvature stacking order on static both single two bay arch are Besides, investigated by considering five different sequences. results present study compared with obtained numerically via ANSYS for validation. It concluded that radius small effect loads, structure, whereas fiber orientation considerably considerable impact such properties.
