On Vibration and Buckling Behaviors of Statically Topology-Optimized CFRP Shell Structures

Abstract

In this study, topology optimization were numerically applied to structural shape optimization problems under static loads for CFRP composite structures. General-purpose finite element analysis code, ANSYS 18.1, was used in the present study, in which the density method (SIMP method), one of the most popular numerical approaches in the structural optimization discipline, was employed for seeking the most efficient structural patterns of the present CFRP under certain fixed weight reduction constrains. From the results of the present study, certain optimal structural patterns or morphologies could be found out for each set of structural and material configurations.
