Multi-Fidelity Analysis of a Composite Beam
Main Article Content
Abstract
The composite ply is made up of two basic components, the fiber and the matrix. The plies are placed together in a mold in a certain order to form a composite laminate. This study presents a method for analyzing the mechanical response of a composite beam from microscopic calculations of the fiber and the matrix. Through the micromechanics and the semi-empirical method to calculate the material properties of the composite ply, using the classical lamination theory (CLT) and the improved Tsai-Wu strength theory to calculate the properties of the composite laminate. Then, using the Euler-Bernoulli beam theory to calculate the mechanical response such as stress, displacement, and safety factor of the composite beam. The results are compared with the experimental results, showing a good agreement.
