Abstract:A 3D model and an estimation of fiber interaction effects during internal instability n non-linear composites are presented Results are based on a micrornechanies solution for a series of fibers embedded in an infinite non-linear incompressible matrix. An ideal bonding between the fibers and the matrix is assumed. Comparison with a limiting case in which the distance bet’ween the neighboring fibers tends to infinity is carried out. It shows the significance of the fiber interaction effects in the considered problem.
Keywords:fiber interaction  instability  non-linear composite
