摘要: Abstract Nonlocal elasticity theory is implemented to investigate the buckling behavior of single-layered graphene sheet (SLGS) embedded in an elastic medium. accounts for small-size effects when dealing with nanostructures such as sheets. Both Winkler-type and Pasternak-type foundation models are employed simulate interaction between surrounding Based on principle virtual work, governing differential equations aforementioned problem derived. Differential quadrature method being numerical solutions loads SLGS obtained. Numerical results show that strongly dependent small scale coefficients stiffness With medium modeled foundation, nonlocal found have decrease–increase–decrease pattern increase
