Abstract: | Within the frame work of a piecewise homogeneous body model, with the use of the three-dimensional geometrically nonlinear
exact equations of elasticity theory, a method is developed for determining the stress distribution in unidirectional fibrous
composites with periodically curved fibers. The distribution of the normal and shear stresses acting on interfaces for the
case where there exists a bond covering cylinder of constant thickness between the fiber and matrix is considered. The concentration
of fibers in the composite is assumed to be low, and the interaction between them is neglected. Numerous numerical results
related to the stress distribution in the body considered are obtained, and the influence of geometrical nonlinearity on this
distribution is analyzed.
