Transverse Vibration and Wave Propagation in an Infinite Thin Elastic Plate with Circular Inclusions : 2nd Report, Cases of a Plate Having Many Circular Elastic Inclusions

Abstract

This paper deals with the problems of flexural wave propagation in an infinite thin elastic plate with circular elastic inclusions. As numerical examples, the problems of plates having two and three circular inclusions with same radius are discussed and influences of incident wave number, radius, separation, and flexural rigidity of the inclusions on the dynamical moment concentration are explored. The results obtained are compared with those of a plate with one inclusion.
