DESIGN AND ANALYSIS OF CANTILEVER BEAM

Abstract

This study investigates the deflection and stress distribution in a long, slender cantilever beam of uniform rectangular
cross section made of linear elastic material properties that are homogeneous and isotropic. The deflection of a
cantilever beam is essentially a three dimensional problem. An elastic stretching in one direction is accompanied by a
compression in perpendicular directions.In this project, static and Modal analysis is a process to determine the stress,
strain and deformation. vibration characteristics (natural frequencies andmode shapes) of a structure or a machine
component while it is being designed. It has become a major alternative to provide a helpful contribution in
understanding control of many vibration phenomena which encountered in practice.In this work we compared the stress
and natural frequency for different material having same I, C and T cross- sectional beam. The cantilever beam is
designed and analyzed in ANSYS. The cantilever beam which is fixed at one end is vibrated to obtain the natural
frequency, mode shapes and deflection with different sections and materials.
