Abstract
We present results of numerical modeling made for the galactic stellar disk embedded in the spherical halo. The non-linear dynamics of bending instabilities developed in the disk is studied. The axisymmetrical bending mode is considered as a main factor increasing the disk thickness. The model dependence between the disk thickness and the halo to disk mass ratio is inferred. The modeling results enable us to estimate the dark halo mass for several edge-on galaxies. The obtained values of for the galaxies considered are of order 1 - 2.
