A frequency domain assurance criterion for frequency response analysis of cracked piezoelectric beam subjected to moving load

A novel frequency domain assurance criterion, called hereby Spectral Assurance Criterion (SAC), is proposed for frequency response analysis of cracked piezoelectric beam under moving load. First, a model of cracked beam bonded with a piezoelectric layer under moving harmonic load is conducted based on the double beam conception and then, analytical expressions of midspan beam deflection (mechanical response) and output charge produced in the piezoelectric layer (electric response) has been established in the frequency domain.
