非线性理想电导率问题中密集夹杂的应力集中

Stress concentration for closely located inclusions in nonlinear perfect conductivity problems

Giulio Ciraolo, Angela Sciammetta

摘要:

本文研究了在各向异性介质中,两个光滑夹杂相互靠近时的应力集中问题。控制方程可以是退化的$p-$ Laplace型,具有$1<p \leq N$。我们证明了最佳的$L^\infty$估计的爆破的梯度的解决方案之间的距离趋于零。

英文摘要:

We study the stress concentration, which is the gradient of the solution, when two smooth inclusions are closely located in a possibly anisotropic medium. The governing equation may be degenerate of $p-$Laplace type, with $1<p \leq N$. We prove optimal $L^\infty$ estimates for the blow-up of the gradient of the solution as the distance between the inclusions tends to zero.
