摘要：

We introduce the use of fiber optic strain sensors embedded within a macromodel composite employed to study and validate micromechanical theories. Fabry-Perot (FP) fiber optic strain sensors (FOSSs) embedded within a macromodel composite are shown to be an accurate and precise means of making local internal strain measurements in and around damage events. The measurements made by the sensors compare closely to those obtained from resistance strain gauge data verified through presently accepted micromechanics. The optical strain sensors effectively measure both the signature of fiber fracture and the resulting strain concentration due to the damage event. The sensors add a new dimension to the validation and development of micromechanics. The approach assists in the formulation of new concepts for interpretation and prediction of actuator/sensor response in smart materials.
