Series form solution for a graded composite strip with elastic variation in span direction

A graded composite strip with elastic variation in span direction is investigated in the paper. So far, studies about materials variation in span direction are rare. Here, the strip is treated as a plane problem, and the modulus varies exponentially with span direction, and Poisson ratio is constant. By using Fourier decomposition in complex form, the series solution for the strip is obtained and is verified by finite element model.
