Abstract
This paper presents the stress concentration and the rigid body motion of a rigid cylindrical inclusion which embedded in elastic infinite medium. In aspect of unaxial incident P-wave, the stress field reduces to a field under a biaxial load Kirsch static solution when the frequency approaching zero. In this paper, we introduce a vertical incident P-wave to eliminate the stress contribution due to Poisson effect so that the stress field reduces to a field under a uniform tension or compression in horizontal direction when the frequency approaching zero. Then we discuss the transient response of a uniaxial Heaviside function incident P-wave in different wave front situation.
