Optimal design of moderate thick laminated composite plates under static constraints using real coding genetic algorithm

Abstract EN

The objective of the current research is to find an optimum design of hybrid laminated moderate thick composite plates with static constraint.

The stacking sequence and ply angle is required for optimization to achieve minimum deflection for hybrid laminated composite plates consist of glass and carbon long fibers reinforcements that impeded in epoxy matrix with known plates dimension and loading.

The analysis of plate is by adopting the first-order shear deformation theory and using Navier's solution with Genetic Algorithm to approach the current objective.

A program written with MATLAB to find best stacking sequence and ply angles that give minimum deflection, and the results comparing with ANSYS.
