SS-V: 2070 Cantilever Beam
Test No. VM08 Perform normal mode dynamic analysis of a cantilevered beam.
Definition
The left end is fully constrained; the back face has a slider constraint to remove the third dimension.
The units are SI.
The material properties are:
- Properties
- Value
- Modulus of Elasticity
- 2e11 N/m2
- Poisson's Ratio
- 0.3
- Mass density
- 8000 kg/m3
