Linear Analysis of Thin-Walled Composite Profiles Weakened by Holes

Abstract The paper presents the results of the numerical analysis of the stability of C-section profiles together with the determination of the influence of the geometrical parameters of the holes and their arrangement on the strength properties of the profile, made of multilayer composite materials in a symmetrical arrangement of layers, which is deformed under the influence of the compressive force. Numerical calculations were carried out in the linear range (solution of the eigenvalue problem - critical state) using the finite element method (FEM) using the ABAQUS calculation package. Based on the obtained results, it was possible to determine the influence of the type and number of holes, their arrangement and geometric dimensions on the values of critical loads as well as the buckling modes of the profiles.
