采用Bövik-Benveniste方法建立了两个弹性球界面相的高阶非完美界面模型。在一个模型中,层的影响通过场变量跨越其边界轨迹的跳跃来解释,而在另一个模型中,通过跨越其中间表面轨迹的相应跳跃来解释。将导出的高阶跳跃条件引入球形颗粒复合材料的单胞模型中,利用多极展开法得到了相应边值问题的精确半解析解.数值算例表明,使用高阶不完善的界面模型提供了一个准确的评估的局部弹性场和整体刚度特性的复合材料与球形界面和/或非相干接口。
Two high order imperfect interface models of elastic spherical interphase are developed using the Bövik-Benveniste methodology. In one model, the effect of the layer is accounted for via jumps in the field variables across the traces of its boundaries, while in the other—via corresponding jumps across the trace of its mid-surface. The derived higher order jump conditions are incorporated into the unit cell model of spherical particle composite and the accurate semi-analytical solutions to the corresponding boundary value problems are obtained by the multipole expansion method. Numerical examples are presented to demonstrate that the use of higher order imperfect interface models provides an accurate evaluation of the local elastic fields and overall stiffness properties of composites with spherical interphases and/or incoherent interfaces.
