The nonlinear static bending analysis of microplates resting on imperfect Pasternak elastic foundations is carried out in this paper. finite element method based the modified couple stress theory used to derive formulations. present and mathematical model are validated by comparisons work’s results with those other reputable publications, which show a very good agreement. influences length-scal...

In this paper, an experimental device is designed for measuring vehicle dynamic load,the structure and stress of the equipment are analyzed by computer technology. The design mainly includes vehicle, road surface, transmission, control [1]. based on a 2-DOF model, Pasternak foundation uses single-chip microcomputer. response vehicles to at different speeds through experiment.

Static analysis of shear deformable plates resting on two-parameter foundations is presented by the method of discrete singular convolution (DSC). The influence of foundation parameters on the deflections of the plate has been investigated. Numerical studies are performed and the DSC results are compared well with other analytical solutions and some numerical results.

In this study, a semi analytical method for transverse and axial vibration of single-walled boron nitride nanotube (SWBNNT) under moving a nanoparticle is presented. The surrounding elastic medium as Pasternak foundation and surface stress effect are included in the formulations of the proposed model. Using Timoshenko beam theory (TBT), Hamilton’s principle and nonlocal piezoelasticity theory, ...
