Mechanisms of stress concentration reduction in fiber composites
A. N. Polilov Blagonravov Institute of Machine Science, Russian Academy of Sciences, Moscow, 101990, Russia
Abstract:
Various models of subcritical fracture that make it possible to explain the significant decrease in the effective stress concentration factor compared with the theoretical value are described for fiber composites with a polymer matrix. The necessity of introducing a material parameter with the dimension of length to describe the scale effect of strength is substantiated. The biomechanical principle of stress concentration reduction by the use of curved fibers flowing around the hole is formulated.
Keywords:
strength, stress concentration, fiber composite, hole, crack, scale effect.
