    Dynamic analysis of uniform and non-uniform cross-section cantilever sandwich beams
    (INESEG Yayıncılık, 2019) Hüseyinoğlu, Mesut; Şen, Murat; Yiğid, Osman; Çakar, Orhan
    In this study, an analytical solution for dynamic analysis of uniform and nonuniformcross-section cantilever sandwich beam is presented. The sandwichbeam was assumed to be an Euler-Bernoulli beam and formed with a thin coreand two thin skin layers. So the shear deformations and rotational effects wereneglected. The equivalent flexural rigidity was obtained for the entiresandwich structure. Some implementations for the solution method are givenand the results are compared with numerical solutions. The usability of theEuler-Bernoulli Beam Theory for thin layered uniform or non-uniformsandwich beams is investigated. The solutions obtained from analytical andnumerical solutions are in good agreement.

    Obtaining Critical Buckling Load of a Cantilever Beam by Using Measured Natural Frequencies
    (Batman Üniversitesi, 2019) Şen, Murat; Hüseyinoğlu, Mesut; Çakar, Orhan
    In this study, buckling critical loads are calculated by using natural frequency values of the first 4 modes obtained by performing experimental modal analysis (EMA) of a uniform cantilever beam. The analytical results are presented with the experimental results comparatively. According to the results it can be said that the vibration data can be used to determine the critical buckling loads of the beams. So there is no need any buckling tests that cause deformation in the test structures or analytical and numerical solutions that need mechanical properties of the beam for obtaining buckling loads.
