Improved rigidity of composite circular plates through radial ribs

Abstract

Engineering practice imposes an increased rigidity of mechanical elements that are parts of machinery or equipment used in practice. Circular plates are such elements, especially used in many common applications, which is why the increase in mechanical properties of circular plates in engineering is connected with the weight optimization problem. The paper makes a study of such a composite plate, proposes and validates a constructive solution capable of increasing the stiffness of this piece. The finite element method is used for the composite panel analysis, and experimental measurements allow us to take information concerning of the magnitude of this rigidity.
