摘要:
通过对层间界面固接的双层复合圆筒中周向导波频散现象的研究,以及与单层筒和层间界面光滑接触的双层复合圆筒频散曲线的比较,发现周向导波在双层复合圆筒中传播时,会发生明显的频散现象,其第一阶模态,在高频时接近于无频散Rayleigh面波。通过对比研究发现,第二阶模态具有在层间界面附近集中能量的特征,可用于层间界面缺陷的周向导波无损检测技术中。该方法可以用来研究确定激励频率的合理范围。
Abstract:
The dispersion phenomenon of the guided circumferential wave propagation in a double-layered hollow composite cylinder with a welded interface is studied.The dispersion curves of double-layered hollow cylinders with a welded interface and a free-sliding interface,and a single-layered hollow cylinder are compared.The results show that the first wave mode of the guided circumferential waves approaches to the Rayleigh wave as the frequency tends to infinity.The present investigation shows that the second wave mode can concentrate larger energy on the area near the interfacial surface.The second wave mode can be applied to the nondestructive check of the interfacial surface defects.The frequency range applicable to such a nondestructive check can be solved by the method presented here.
