Mechanical analysis of non-uniform beams resting on nonlinear elastic foundation by the differential
quadrature method
Ming-Hung Hsu

 
Abstract
    A new approach using the differential quadrature method (DQM) is derived for analysis of non-uniform beams resting on nonlinear media in this study. The influence of velocity dependent viscous damping and strain rate dependent viscous damping is investigated. The results solved using the DQM have excellent agreement with the results solved using the FEM. Numerical results indicated that the DQM is valid and efficient for non-uniform beams resting on non-linear media.
 
Key Words
    DQM; non-uniform beam; nonlinear media; mechanical behavior.
