Abstract. Mechanic-mathematical models of surface fiber optic piezoelectroluminescent (PEL) sensors installed on the surface of polymer composite structures, in particular, plates (shells) for refined monitoring of inhomogeneous "gradient" deformation fields inside structures, have been developed. There are given problem statements and problem solving algorithms for representative domain of "plate/sensor" system in order to find numerical values of control and informative, including transfer "gradient" coefficients of PEL-sensors. Results of numerical calculation of control and informative transfer coefficients of surface PEL-sensor for case of small values of gradients of diagnosed membrane, bending and torsional deformations of transversal-isotropic elastic plate are presented.
Key words: piezo-electro-elasticity, mechanical-luminescent effect, optical fiber, surface sensor, composite plate, numerical modeling.
