【摘要】 <正>We discuss the construction of quasi-optimal energy based atomistic/continuum(A/C)coupling methods for crystalline solids with defects,based on tools from numerical analysis.For general multi-body interactions on the 2D triangular lattice(and potentially for 3D lattices),we show that ghost force removal(patch test consistent)A/C methods can be constructed for arbitrary interface geometries.更多还原
