摘要：

This chapter discusses the stress gradient theories of Eringen and Aifantis in terms of their original formulations, their differing dispersion properties in dynamics, and their finite-element implementation. A proposed combination of the two provides a dynamically consistent gradient enrichment while avoiding implementation difficulties.
