A short, thin-walled uniform shear beam clamped at the base vibrates freely. Determine the first two modes of
vibrations neglecting all flexural deformations. Figure 202.1 Shear Beam Problem Sketch Material Properties
E = 200 GPa
υ = 0.27
ρ = 7860 Kg/m3 Geometric Properties
L = 30 m
W = 10 m
t = 0.1 m Analysis Assumptions and Modeling Notes
Flexural deformations were eliminated by requiring all nodes with the same Z coordinate value to be coupled
in UX and UY. Since this is a square beam, the frequenc...
