Nonlinear torsional mechanical properties of ZNO nanowire based on completely nonlocal theory

To study the torsional mechanical properties of ZnO nanowires, solve the following three questions. 1. Due to the small scale effect and surface effect of ZnO nanowires, the traditional theory of continuum mechanics and macroscopic experimental methods are difficult to accurately predict nano scale mechanical properties of materials, the use of nonlocal elasticity theory can study the mechanical properties of nanoscale materials research provides a more accurate analysis. 2. Based on elasticity, establish mechanical model of ZnO nanowires twist, employ nonlocal theory to derive its mechanical equations, study the effects of different lengths of nanowires to the torsional mechanical properties of ZnO nanowires. 3. When changing the characteristic properties of ZnO nanowires and found that the mechanical properties change with reversing and present nonlinear distribution.
