The document details a project analyzing cantilever beams of various cross-sectional shapes (I, C, T) and materials (steel, stainless steel, cast iron) using static and modal analysis in ANSYS. It includes steps for solid modeling, material property assignment, and results comparison, concluding that cast iron performs better in terms of stress and natural frequency for the cantilever beam structure. The analysis reveals that I-section beams exhibit lower deformation and stress values compared to other sections.

1. PROJECT OBJECTIVE
 A beam is a structural element that is capable of
withstanding load primarily by resisting against bending
 A beam can be made of wood, concrete, steel depending
upon need
 The bending force induced into the material of the beam

50. CONCLUSION
 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.
 By observing the static analysis the deformation and
stress values are less for I-section cantilever beam at
cast iron material than steel and stainless steel.
 By observing the modal analysis results the deformation
and frequency values are less for I-section cantilever
beam more for T-section.
 So it can be conclude the cast iron material is better
material for cantilever beam in this type I-section model.
