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 any way to speed up inverse of large matrix?

I'm working on some dynamic problems, and often we need to determine the inverse of a matrix of order 50x50 and larger. I need to speed up the process.
