提出了一种复合材料刚度识别的新方法。通过一个反向传播神经网络 ,利用正交各向异性板的动态特性(固有频率 )识别复合材料板刚度。同时给出了实例用来验证此方法的有效性 A new method to identify the stiffness of composite materials is proposed. Using a backpropagation neural network, the stiffness of the composite panel is identified using the dynamic properties of the orthotropic plates (natural frequencies). At the same time, an example is given to verify the validity of this method
