Buckling analysis of double – bonded micro beam based on Reddy – Levinson model using differential quadrature method

In this paper, the linear buckling analysis of double – bonded micro - beam was carried out based on the Reddy-Levinson model and the modified strain gradient theory. The studied system consists of an isotropic micro - beam and a magneto-electro-elastic composite micro beam. The beams are connected by an enclosing elastic medium and were simulated according to the both Winkler and Pasternak models. In order to verify the outcomes, they were compared with the available published data. The comparison shows that the results are in a good agreement with other research outcomes.The results show that as the Winkler and Pasternak constants increase, the critical buckling load decreases along the ratio of the thickness to the material length scale parameter. Moreover, the results confirm that the addition of a magneto-electro-elastic composite micro beam of the system, including anisotropic micro - beam lead to the reduction of the critical buckling load.
