摘要: AbstractThis paper presents dynamic stability analysis of beams with shear deformation and rotary inertia subjected to periodic axial forces by employing a discrete singular convolution (DSC) algorithm regularized Shannon kernel. The effect has been taken into account based on Engesser’s Haringx’s theories, respectively. A modified is proposed solve the governing equations beam motion. influence inertia, deformation, damping instability regions investigated. obtained numerical results are compared those existing method. Numerical indicate that reliable approach for solutions this kind problem in investigation. differences between theories also presented.
