研究了在环境条件下,含界面缺陷(间隙)的智能贴片/层合接头在动态时谐机械载荷和电载荷作用下的响应。为了找到一个封闭的解析形式的轴向位移,剪应力和界面脱粘长度的一维修改,剪滞分析。在给定的关节几何形状和三个不同的位置的差距,遗传算法被实施,以找到一个消失/最小的脱粘长度确保的模型参数的值。此外,对于每个最优解的影响的差距的长度以及模型参数上的界面脱粘长度的长度进行了调查。
The study deals with the response of a smart patch/layer joint with interface defect (gap) subjected to dynamic time harmonic mechanical and electric load at environmental conditions. In order to find the axial displacements, shear stress and interface debond length in a closed analytical form a 1D modified, shear lag analysis is used. At given joint geometry and three different positions of the gap, a genetic algorithm is implemented to find the values of the model parameters at which a vanishing/minimal debond length is ensured. Moreover, for each optimal solution the influence of the length of the gap as well as the model parameters on the length of the interface debond length is investigated.
