Stress Wave Propagation Discipline and Simulation Analysis in Non-homogeneous Laminated Composites

摘要

Application of stress wave testing methods can realize non-destructive testing of composites, but non-homogeneous characteristics of composites determine the complexity of stress wave propagation. Using the stress wave theory to explain the propagation principle, to describe the stress situation in the composites, which is meaningful to perfect the stress wave testing method. In this paper, stress wave propagation principle of non-homogeneous laminated composites has been revealed, mathematical descriptions of stress wave propagation are also given, and finite element simulation method has been used to verify the theory.
