Abstract:A comparison is made of the finite differences as a sum-accelerated pseudospectral method (FDSPM) and the discrete singular convolution (DSC) algorithms in free vibration analysis for the first time. Taylor series expansion method is used to eliminate the friction points. Some important issues on these numerical methods are addressed from the practical application point of view. © 2019 Elsevier Ltd
