围压应力是一个加权的静态维里应力
Peridynamic stress is a weighted static Virial stress
摘要：
Lehoucq和Silling（2008）提出的围压应力张量在数值计算中实现起来很麻烦。本文指出，围压应力张量具有Irving和Kirkwood（1950）导出的加权静态维里应力的数学表达式，它为围压应力张量的数值计算提供了一个简单明了的表达式。
英文摘要：
The peridynamic stress tensor proposed by Lehoucq and Silling (2008) is cumbersome to implement in numerical computations. In this note, we show that the peridynamic stress tensor has the mathematical expression of a weighted static Virial stress derived by Irving and Kirkwood (1950), which offers a simple and clear expression for numerical calculations of peridynamic stress tensor.
