Özet:

   In this study, the buckling loads and free vibrations of axially loaded cantilever composite beams supported with and without elastic Winkler foundation are investigated for different temperature parameters. It was assumed that beam is laminated and symmetric about the midplane axis. Solution of the problem is satisfied by the finite element method based on the Euler Bernoulli beam theory. The buckling load and free vibration values are calculated by a finite element code developed in MATLAB for the simulation of the problem. Change in the buckling load and free vibration values with respect to temperature for laminated composite beams in different layer angles are investigated. Also, effects of axial loads and Winkler parameters on the buckling load and free vibration values are investigated for different beams designs.
