AI总结:

针对周期域中的次近邻对相互作用模型,提出准非局部准连续方法(QNL-QC)的事前和事后分析,确保原子解与QNL-QC解之间的一一对应关系。

摘要:

对于周期域中的次近邻对相互作用模型,提出了准非局部准连续方法(QNL-QC)的事前和事后分析。结果适用于大变形,并基本保证了原子解与QNL-QC解之间的一一对应关系。该分析基于负范数中的截断误差和残差估计以及新颖的事前和事后稳定性估计。

英文摘要:

For a next-nearest neighbour pair interaction model in a periodic domain, a priori and a posteriori analyses of the quasinonlocal quasicontinuum method (QNL-QC) are presented. The results are valid for large deformations and essentially guarantee a one-to-one correspondence between atomistic solutions and QNL-QC solutions. The analysis is based on truncation error and residual estimates in negative norms and novel a priori and a posteriori stability estimates.
