摘要：
Based on the theory of elastic dynamics, scattering of elastic waves and dynamic stress concentrations in fiber-reinforced composite with interfaces are studied, analytical expressions of elastic waves in different medium area are presented and an analytic method to solve this problem is established. The mode coefficients are determined by means of the continuous conditions of displacement and stress on the boundary of the. interfaces. The influence of material properties and structural size on the dynamic stress concentration factors near the interfaces is analyzed. It indicates that they have the clear influence to the dynamic properties of fiber-reinforced composite. As examples, the numerical results of dynamic stress concentration factors near the interfaces are presented and discussed. This paper provides a reliable theoretical evidence for the study of dynamic properties in fiber-reinforced composite.
