In this study, torsional wave propagation is investigated in a rod that are made of one and two dimensional functionally graded material. Firstly, the governing equations of the wave propagation in the functionally graded cylinder derived in polar coordinate. Secondly, finite difference method is used to discretize the equations. The Von Neumann stability approach is used to obtain the time ste...

Abstract Determining the composition of a mixed material is an open problem that has attracted interest researchers in many fields. In our recent work, we proposed novel approach to determine using convolutional neural networks (CNNs). machine learning, model “learns” specific task for which it designed through data. Hence, obtaining dataset materials required develop CNNs estimating compositio...
