Abstract :
The A multiscale computational method (CADD) is presented for modeling of materials at nanoscale whereby a continuum region containing defects is coupled to a fully atomistic region. The method reduces the degree of freedom in simulations of mechanical behavior of nanomaterials without sacrificing important physics. Applications to nanoindentation are used to validate and demonstrate the capabilities of the model.
