The initial buckling behavior of flat and curved fiber metal laminate panels. By Koos Verolme. Abstract. Local buckling is expected to become an important design issue when metallic materials in conventional stiffened panels are replaced by fiber metal laminates. An experimental study to validate the use of existing design methods for the Author: Koos Verolme. In the present study, the buckling of laminated composite curved panels embedded with Shape Memory Alloy (SMA) fibers under different geometrical conditions was studied. The buckling load of curved panels subjected to axial, lateral and mixed loads was analyzed. Different distributions of SMA fibers were by: In addition, results illustrating the effects of laminate orthotropy and anisotropy and panel curvature on the panel response are presented. The results indicate that panel curvature can have a significant effect on the nonlinear and buckling behavior of the panels subjected to combined loads. the buckling strength for large hole sizes, and that for the same-sized plates and same cutout areas, the square hole cases exhibited slightly stronger “anomalous” buckling behavior. This buckling study needed to be extended to the cases of laminated composite plates with cutouts.
In terms of buckling and postbuckling behaviour flat and curved fibre-metal laminate panels were first investigated by Verolme,,. Results showed that FML panels exhibited similar buckling and postbuckling behaviour to their metallic counterparts. Fiber metal laminates (FMLs) are composed of thin (– mm thick) metal layers alternating with composite plies. To provide an appropriate adhesion, the metal layers are subjected to a special surface treatment, whereas the preimpregnated with resin, high-strength fibers are used to form the composite layers having a unidirectional, cross-ply, or fabric structure. J.L. Verolme, The initial buckling behavior of flat and curved fiber metal laminate panels. Delft University of Technology, Faculty of Aero. Eng, Report LR, results into predicted laminate behavior. Furthermore, it covers loading situations and structural re-sponses such as buckling, creep, relaxation, fatigue, durability, and vibration. BASIC LAMINA PROPERTIES AND MICROMECHANICS The strength of any given laminate under a prescribed set of loads is probably best determined by conducting a test.
An experimental study to validate the use of existing design methods for the initial buckling and postbuckling of flat and curved unstiffened fiber metal laminate panels is reported on. All. Unlike the flat panels, in the curved ones, buckling load of laminates with near to surface delamination is lower than the same laminates with middle surface delamination. Starting to debond in the curved panels is suspended, but the amount of reduction in load bearing after unstable delamination growth is higher compared to the flat panels.
