摘要：
The influences of temperature variations on the use of wave propagation for damage detection are investigated for use with impedance-based structural health monitoring. The equations used to determine the damage based upon a longitudinal wave are presented as derived by Kabeya, et al. Equations are defined in order to determine the damage location in a simulation. Temperature variations are induced, and the resulting errors are presented. A possible application using a realistic temperature differential is proposed. A curve-fit of the modulus of elasticity is implemented to correct damage location error.
