Abstract: Every mechanical structure exhibits natural modes of vibration. Beams with variable cross section and material properties are frequently used in aeronautical, mechanical and civil engineering. Given the elastic and inertia characteristics of the structures, modes of vibration can be computed, the study being known as modal analysis. This paper presents modal analysis of simply supported beam using different materials. Comparison of natural frequency of the beam considering various materials is done analytically and also using ANSYS APDL. Effect of change of length and cross sectional area on natural frequency is also studied. Comparative study on natural frequency of sandwich beam using various materials is done analytically and also using ANSYS APDL

Keywords: Natural Frequency, Mode Shape, Sandwich Beam.
