The eigenfrequencies and mode shapes of a simple beam are calculated based on . During the calculation procedure, It is assumed that:
- There is no structural coupling between the different degrees of freedom of the beam
- The beam is homogeneous
- The beam is un-damped
- there are free oscillations
Four boundaries conditions are included:
Two Geometries are available:
- rectangular beam
- eigenModes.m: a function used to compute the eigenfrequencies and modes shapes of a continuous beam with different boundaries conditions.
- Example.m is an application of this function.
