An analytical solution is presented to predict the thermal stress and strain induced by atemperature change on an optic-fiber sensor surface bonded onto a host structure. It shows thatthe thermal strain transferred from the host material to the optic-fiber is heavily affected by thebonding characteristics including the optic-fiber, protective coating, adhesive and host material.Experimental tests were conducted using a fiber Bragg grating sensor to evaluate the thermal strainon the surface-bonded optic fiber. The accuracy of the theoretical prediction was validated by theexperimental results. Experimental measurements matched well with the analytical predictions.
