摘要:
首次对界面层存在时周向导波在多层圆筒中传播问题进行理论推导,并对理论结果进行相应的数值计算。结果表明:频散现象和模态干涉现象在多层圆筒中传播时也同样出现; 通过与理想的固结连接和理想的光滑连接类比发现,界面层存在时,对频散曲线和合成位移都有明显的影响,这与界面材料的Lamé常数和界面层的厚度有关。因此,工程上要根据实际需要的理想边界状况,选用合适的材料作为界面层。
Abstract:
The guided circumferential wave propagation with a interface in multi-layered thick-walled ho-llow cylinder was firstly investigated theoretically and the numerical calculation was completed.Results showed that dispersion phenomenon and mode interactions occurred in multi-layered thick-walled hollow cylinder.Comparing with those cylinders with ideal sliding or ideal welded interface,the dispersion curves and the resultant displacements were distinctly influenced by the existence of interface in multi-layered cylinder,thus it is related to Lamé constant and the thickness of the interfaces.It was suggested that the material of interfaces should be selected according to practical needs.
