Raftoyiannis, IGKounadis, ANA simplified but very reliable approach for the postbuckling analysis of pultruded composite bars and simple two-bar frames using the classical lamination theory is comprehensively presented. The overall postbuckling responses for symmetric I-structural shapes made from commercially available composite and homogeneous materials are thoroughly discussed. This leads to the optimum design of the structures under consideration. A simple stability criterion is also established for a direct determination of the critical loads. Two numerical examples are used to illustrate the simplicity and efficiency of the proposed procedure.http://hdl.handle.net/123456789/1240210.2514/2.4812188735ISI:A1997YJ0780001218810001-1452engAMER INST AERONAUT ASTRONAUTAIAA JournalDELAMINATIONBEAMSPostbuckling analysis of pultruded composite bars and simple framesjournalArticle1997Δημοσίευση σε περιοδικόPublication in journalΑεροδιαστημική μηχανικήAerospace Engineeringisi - Engineering, Aerospace includes resources concerned with astronautics, aeronautics, aerospace, and aviation.
