Boundary Conditions In The Indeterminate Couple Stress Model: New Perspectives
Aifantis International Symposium (2nd Intl. symp. on Multiscale Material Mechanics in the 21st Century)[Gradient Elasticity ]
Back to Plenary Lectures »

Abstract:
We reconsider the Toupin-Mindlin indeterminate couple stress model being one of the prominent gradient elasticity models. While abundantly used for the description of nano-sized materials, some theoretical issues concerning boundary conditions and constitutive assumptions need discussion. We provide an improved set of independent boundary conditions making it possible to uniquely identify material properties. In addition, we highlight the connections to the more general gradient elasticity models.
