SCATTERING OF STEADY INCIDENT SH-WAVE BY CIRCULAR ARC LINING AT THE CORNER POINT OF RECTANGULAR PLANE

  • Wave function expansion method is used to study the scatteringof steady incident plane SH-wave by circular arc elastic lining at thecorner point of a rectangular plane. The total wave solutionsinside and outside the lining are constructed, which satisfy the free stressconditions of the two rectangular boundaries; all unknowncoefficients in the scattering solutions and the refraction wavesolutions are determined by solving the linear equations with the conditions of displacement/stress at the boundaries of thecircular lining. An example is given to illustrate the variations ofDTSCF(dynamic tangential stress concentration factor) and amplitude ratio ofthe points at the interior boundary of the circular lining vs dimensionlesswave numbers and incident angles. The results of the example show that theDTSCF and the amplitude ratio are magnified to some extent.
