Abstract

Cantilever-based nanostructures have attracted widespread attention in nanoengineering. As key components of cantilever-based nanosensors, some cantilever nanoplates are exposed to magnetic fields in working conditions. This paper performs the buckling analysis of magnetically affected cantilever nanoplates resting on elastic foundations. The aim of the presented research is to discuss the effects of magnetic fields on the buckling characteristics of cantilever nanoplates. Based on Eringen’s nonlocal elasticity theory, the exact buckling solutions of the cantilever nanoplates are obtained by using symplectic approach incorporating a superposition technique. To resolve the difficulties in dealing with the complex boundary value problems of cantilever nanoplates, the buckling problem is divided into two sub-problems which can be analytically solved by the symplectic approach. Exact solutions of the buckled cantilever nanoplate are derived by a superposition of the obtained solutions for sub-problems. Comparisons are presented to show the accuracy and stability of the proposed method. Parametric studies of the in-plane magnetic field and elastic foundation on the buckling characteristics of cantilever nanoplate are also given. Highly accurate critical buckling loads and buckling mode are derived analytically. This study has shown that applying magnetic field is an effective way to control the critical buckling loads and buckling mode shapes of cantilever nanoplates.

Abstract

Abstract: A Hamiltonian‐based methodology is presented to study the fracture behaviors of the thermo‐viscoelastic materials based on the Laplace transform. The governing equations and associated boundary conditions are rebuilt in a Hamiltonian form by using the symplectic mathematics in the frequency domain (s‐domain). The fundamental unknown vector composed of both displacements and stresses variables is expanded in terms of the symplectic eigensolutions. The corresponding unknown coefficients of the symplectic series are determined from the outer boundary conditions. Thus, the main unknowns are obtained and transformed into the time domain (t‐domain). The fracture parameters including stress intensity factors (SIFs) and J‐integrals are derived simultaneously. Numerical examples as well as convergence studies are given and are found to be in good agreement with the ANSYS results. A parametric study of thermo‐viscoelastic parameters is included also.
