Localized elastic fields in periodic waveguides with defects
S. A. Nazarov Institute of Problems of Mechanical Engineering, St. Petersburg, 199178, Russia
Abstract:
The variational method for determining localized waves (trapped modes) is modified for periodic elastic waveguides with partially clamped surfaces. Two sufficient conditions for the existence of localized fields in waveguides with defects (cavities with positive volume and cracks) are established. In the presence of elastic and geometrical symmetries, localized fields were also found in periodic elastic waveguides with surfaces free of external loads.
Keywords:
periodic waveguide with defects, localized elastic fields, variational method.
