||Nanocomposites, nanofiber, stress distribution, geometrik nonlinearty,
||In the framework of the piecewise homogeneous body model with the
use of the three-dimensional geometrically nonlinear exact equations of the theory
of elasticity, the method developed for the determination of the stress distribution
in the nanocomposites with unidirectional locally curved and hollow nanofibers is
used to investigate the normal stresses acting along the nanofibers. Furthermore, it
is assumed that the body is loaded at infinity by uniformly distributed normal forces
which act along the nanofibers and the crosssection of the nanofibers and normal
to its axial line, is a circle of constant radius along the entire nanofiber length.
For the solution of considered boundary value problem, an approximate analitical
method is developed by using the boundary form perturbation method. The numerical
results related to stress distribution in considered body and the influence of
geometrical nonlinearity to this distribution are presented and interpreted.
