Numerical analysis of deformation processes in the optical fiber sensors

In this paper the deformation processes taking place in system of the substrate-adhesive-fiber optic sensor are presented. The task in the theory of linear viscoelasticity. The decision was made numerically using finite-element package ANSYS, to deal with the procedure step method of integration. Deformation distribution on length of the fibre-optical sensor is defined, thanks to it is minimum admissible length of the sensor is established. Dependences for various cases of loads are received and sensor models, evolution of deformations in the sensor is certain. It is revealed, that use of cover DeSolite 3471-1-152А is inadmissible, owing to falling of deformation more than 10 times for a small time interval.
