Multiscale modeling for contact problem with high-contrast heterogeneous coefficients with primary-dual formulation
Zishang Li, Changqing Ye, Eric T. Chung
In this paper, we propose a novel iterative multiscale framework for solving high-contrast contact problems of Signorini type. The method integrates the constrained energy minimizi…

A locking free multiscale method for linear elasticity in stress-displacement formulation with high contrast coefficients
Eric T. Chung, Changqing Ye, Xiang Zhong
Achieving strongly symmetric stress approximations for linear elasticity problems in high-contrast media poses a significant computational challenge. Conventional methods often str…

Efficient numerical method for the Schrödinger equation with high-contrast potentials
Xingguang Jin, Liu Liu, Xiang Zhong +1
In this paper, we study the Schrödinger equation in the semiclassical regime and with multiscale potential function. We develop the so-called constraint energy minimization general…
