Is there an efficient way to determine only the first (smallest) eigenvalues of the matrix?

I need to determine only the first natural frequency of the elastic beam, in order to continue to take the optimization of certain parameters of the beam. Given that the proposed model matrix...

Is there clear limits to the value of the deflection and slope of which goes to the assumption of small elastic deformations of the cantilever beam?

I work on some approximate method for analysis of elastic Euler-Bernoulli cantilever beam. There is a concentrated mass on beam tip. Method works exelent for m/M5. I assume that the higher values...

Is there a way to form a 3x3 stiffness matrix for bending in the plane of a Timoshenko beam?

I want to introduce the slope of this kind of beam as the sum of the angle due to bending and angle due to the shear. I know that the typical stiffness matrix for this case dimensions 2x2.

Is there a typical example of cantilever beam for which there is an obvious difference between Euler Bernoulli and Timoshenko beam theory?

I work on some eigenfrequencies analysis of that kind of beams, and still search for ''good'' dimension ratio.
