应用改进的一维剪滞分析方法研究了在环境条件下、动态时谐载荷和电载荷作用下,沿着搭接区有和无界面间隙的智能贴片/层结构的湿热压电响应。重叠区分为3个部分,其中2个属于界面的完整部分,1个属于差距的长度。所有这三种类型的封闭形式的解析解的推导和获得。以PZT-5 H/CFRP结构为例,对两种界面情况(连续或有间隙)的模型剪切应力、电梯度、应力和脱粘长度进行了比较。所有结果均以图表显示并进行了讨论。
The modified 1D shear lag analysis is applied to study the hygro‐thermal‐piezoelectric response of a smart patch/layer structure with and without an interface gap along the overlap zone at environmental conditions and under dynamic time harmonic and electrical loads. The overlap zone is divided into 3 parts – 2 of them belong to intact parts of the interface and 1 of them to the length of the gap. All three types of closed form analytical solutions are derived and obtained. The comparison of the model shear stress, electric gradient, stresses and debond length for both cases of the interface (continuous or with a gap) is done at an example of a PZT‐5H/CFRP structure. All results are shown in figures and discussed.
