摘要：
The size-dependent behaviour of elastic beams is investigated using Bernoulli-Euler kinematics. The two-phase stress-driven integral elasticity is adopted to model size effects. Biaxial bending is considered and an effective coordinate-free solution procedure is proposed. The corresponding governing equations of non-local elasticity are established and discussed. The contributed theoretical results could be useful for the implementation of procedure oriented to design and optimization of modern sensors and actuators.
