复合材料椭圆方程组在窄域上的估计
Estimates for Elliptic Systems in a Narrow Region arising from Composite Materials
摘要:
本文建立了一类椭圆型方程组(包括弹性力学的线性系)在一般窄域中的全维解的梯度的逐点上、下界。这一问题源于对高对比度复合材料损伤分析的研究。结果表明,损伤可能是从最西处开始的。
英文摘要:
In this paper, we establish the pointwise upper and lower bounds of the gradients of solutions to a class of elliptic systems, including linear systems of elasticity, in a general narrow region and in all dimensions. This problem arises from the study of damage analysis of high-contrast composite materials. Our results show that the damage may initiate from the narrowest place.
