Guided wave propagation in assymetrical corrugated plates
Research on guided wave propagation in isotropic flat plates has been quite intensive in the past decade. However, the research on guide wave propagation in corrugated plate limited only to symmetrical type whilst the asymmetrical type has not been determined. Therefore, the behaviour of guided wave...

Research on guided wave propagation in isotropic flat plates has been quite intensive in the past decade. However, the research on guide wave propagation in corrugated plate limited only to symmetrical type whilst the asymmetrical type has not been determined. Therefore, the behaviour of guided wave in asymmetrical corrugated plates still remains unknown. Hence, in the present study, guided wave dispersion curve for asymmetrical corrugated plates and effects of corrugated dimensions on the dispersion curves are determined. Two-dimensional and infinite plate with isotropic material is modelled by numerical method. Two parameters are affecting the results of dispersion curve which are corrugation height and half wavelength. The results show that the mode shapes are easier to identify if smaller ratio of corrugation height and half wavelength is used. The dispersion curve is reasonably well for small corrugation height but not so good for large corrugation height. |
