Cantilever Beam Modal Analysis

Created using ANSYS 13.0

Problem Specification

Consider an aluminum beam that is clamped at one end, with the following dimensions.


4 m


0.346 m


0.346 m

The aluminum used for the beam has the following material properties.


2,700 kg/m^3

Youngs Modulus

70x10^9 Pa

Poisson Ratio


Using ANSYS Workbench find the first six natural frequencies of the beam and the mode shapes.
