The complex boundary of the elliptical inclusion rendered it difficult
to solve the problem of wave scattering. In this study, the steady-state
response was analyzed using the wave function expansion method.
Subsequently, the Ricker wavelet was employed as the transient
disturbance and Fourier transform was used to determine the distribution
of transient dynamic stress concentration around the elliptical
inclusion. The effects of wave number, elliptical axial ratio and
difference in material properties on the distribution of the dynamic
stress concentration around the elliptical inclusion were evaluated. The
numerical results revealed that the dynamic stress concentration always
appeared at both ends of the major axis and minor axis of the elliptical
inclusion, and the difference in material properties between the
inclusion and medium influenced the variations in the dynamic stress
concentration factor with the wave number and elliptical axial ratio.
