  4. Abstract:
  5. In this article, the buckling behavior of a nanoplate at the bottom of the channel over which the fluid passes with a one-dimensional flow was investigated. Navier–Stokes equations were used to obtain the applied force from the fluid to the nanoplate. Nonlocal elasticity theory was used to consider nanoscale effects, and this problem was solved using Galerkin’s weighted residual method. In previous research, the buckling behavior of nanoplates was done with the assumption of buckling in a vacuum, but in this study, the environment around the nanoplate is assumed to be a flowing viscous fluid. According to the results presented in this study, the critical buckling load of nanoplates coupled with fluid declines with the increase in the nonlocal parameter. Increasing the velocity of the fluid in contact with the nanoplate leads to a rise in the critical load of the nanoplate for all nonlocal parameter values and different modes, and the critical load value rises compared to the buckling in a vacuum. Compared to fluid density, fluid viscosity has less effect on changing the buckling behavior of nanoplates. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature
