Constitutive Modeling of the Mechanical Properties of Optical Fibers

摘要

Micromcchanical modeling of the composite mechanical properties of optical fibers was conducted]. Good agreement was obtained between the values of Young’s modulus obtained by micromcchanics modeling and those determined experimentally for a single mode optical fiber where the wave guide and the jacket are physically coupled. ‘l’he modeling was also attempted on a polarization-maintaining optical fiber (PANDA) where the wave guide and the jacket arc physically decoupled, and found not to applicable since the modeling required perfect bonding at the interface. The modeling utilized constituent physical properties such as the Young's modulus, Poisson’s ratio, and shear modulus to establish bounds on the macroscopic behavior of the fiber.
