SCATTERING OF STEADY INCIDENT SH-WAVE BY CIRCULAR ARC LINING AT THE CORNER POINT OF RECTANGULAR PLANE
直角平面角点衬砌对稳态平面SH波的散射

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