标量Hencky塑性的连续性方程和特征流

Continuity equation and characteristic flow for scalar Hencky plasticity

Jean-Francois Babadjian, Gilles A. Francfort

摘要:

我们调查的唯一性问题所产生的最简单的模型,Hencky塑性连续性方程。相关系统的形式为$\rm{ curl\;}(μσ)=0$,其中$μ$是非负测度,$σ$是二维无发散单位向量场。在建立该领域的Sobolev正则性,我们提供了一个精确的描述的所有可能的几何形状的特征流,以及相关的解决方案。

英文摘要:

We investigate uniqueness issues for a continuity equation arising out of the simplest model for plasticity, Hencky plasticity. The associated system is of the form $\rm{ curl\;}(μσ)=0$ where $μ$ is a nonnegative measure and $σ$ a two-dimensional divergence free unit vector field. After establishing the Sobolev regularity of that field, we provide a precise description of all possible geometries of the characteristic flow, as well as of the associated solutions.
