摘要

二阶梯度模型通常是非局部的。近年来发展了局部二次梯度模型。它们可以看作是服从运动约束的微结构介质的一种特殊情况。这样就很容易建立一个大应变有限元方法,既适用于一维问题,也适用于二维或三维问题。最后给出了一个一维的例子。

Second gradient models as a particular case of microstructured models: a large strain finite elements analysis

Second gradient models are usually non local. Recently local second gradient models have been developed. They can be seen as a particular case of microstructured media which obey a kinematic constraint. It is then easy to build up a large strain finite element method useful for 1D as well as for 2D or 3D problems. A one-dimensional example is finally given.
