本文提出了一种利用分布式压电作动器/传感器和传递函数概念的复合材料层合板分层损伤识别技术。在这种技术中，阵列的致动器/传感器的配置是精心设计的，以提高效率的识别算法的基础上的传递函数。通过梁的算例，研究了该方法的特点和有效性。实验数据模拟自适应复合材料层合板高阶板理论的有限元技术，扩展为脱层的层合板通过实施在脱层前的位移连续性条件。
In this article, an identification technique for detecting delaminations in composite laminates is proposed, which uses the distributed piezoelectric actuators/sensors and the conception of transfer function. In this technique, the configuration of arrays of actuators/sensors is carefully designed to enhance the efficiency of the identification algorithm based on the transfer function. A beam example is employed to study the characteristics and effectiveness of the present identification approach, numerically. The experimental data are simulated from a FEM technique of higher-order plate theory for adaptive composite laminates, which is extended for delaminated laminates by implementing the displacement continuity conditions at the delamination front.
