Comparisons of the responses of the plate calculated by both the analytical and the FEA methods for the air-backed case when 𝑡=0.45 ms: (a) the deflection 𝑤 of the back face of the plate calculated by the analytical method; (b) the deflection 𝑤 of the back face of the plate calculated by the FEA method; (c) the von Mises stress 𝜎_𝑚 of the back face of the plate calculated by the analytical method; and (d) the von Mises stress 𝜎_𝑚 of the back face of the plate calculated by the FEA method.
