Vibration and Buckling Analysis of Composite Plate Using FEA

In order to achieve a numerical solution to the governing differential equations, the finite element technique, also known as FEM, is used. The buckling analysis of rectangular laminated plates with rectangular cross-sections is explored for a variety of boundary condition and aspect ratio combinations. Buckling loads are analysed and verified with respect to other works that may be found in the relevant body of literature in order to establish whether or not the current method is accurate. The trustworthiness of the finite element approach that was used is shown by the substantial agreement with the other data that was provided. New numerical findings have been developed for uniaxial and biaxial compression loads on symmetrically laminated composite plates. These results concentrate on the important impacts of buckling for a variety of factors, including boundary condition, aspect ratio, and modular ratio. It was discovered that the influence of boundary conditions on buckling load rises as the aspect ratio increases for both uniaxial and biaxial compression loading. This was the case regardless of whether the loading was uniaxial or biaxial. It was also discovered that, at larger values of elastic modulus ratio, the variation of buckling load with aspect ratio becomes virtually constant.
