Adaptive mesh refinement and local/non-local transition in the local quasicontinuum method are studied in this paper. Although deformation gradients have been used to determine the mechanical state of an element in the original quasicontinuum method, we adopt elastic stiffness coefficients which govern stress-strain relations at finite deformation and do not require reference atomic positions. Confirming its availability, we perform nano-indentation simulations in the two dimension.
