受局部到非局部耦合约束的界面识别

Interface Identification constrained by Local-to-Nonlocal Coupling

Matthias Schuster, Volker Schulz

AI总结:

本文针对界面识别问题,提出将基于能量的局部到非局部耦合作为约束条件,结合偏微分与非局部算子以兼顾模型适用性与计算成本。

摘要:

使用非局部算子的物理现象模型在某些应用中比采用偏微分算子的经典模型更合适。然而,这些非局部问题的数值求解可能非常昂贵。因此,出现了将偏微分算子与非局部算子结合的局部到非局部耦合。在本研究中,我们利用基于能量的局部到非局部耦合,作为界面识别问题的约束条件。

英文摘要:

Models of physical phenomena that use nonlocal operators are better suited for some applications than their classical counterparts that employ partial differential operators. However, the numerical solution of these nonlocal problems can be quite expensive. Therefore, Local-to-Nonlocal couplings have emerged that combine partial differential operators with nonlocal operators. In this work, we make use of an energy-based Local-to-Nonlocal coupling that serves as a constraint for an interface identification problem.
