The predicted strain field in the stretching of a 1-D elastic bar. The bar is partitioned into local and nonlocal subregions. With the new coupling method, there is zero error in the transition regions between local and nonlocal equations for this particular example problem. Nonlocality, incorporating a length scale within the equations of mechanics, is increasingly recognized as an essential aspect of high-fidelity modeling of the fracture and failure of solids. The nonlocal [...]
