Indentation is a remarkably flexible mechanical test due to its relative experimental
simplicity. Coupled with advances in instrument development, ease of implementation has …

Using molecular-dynamics simulation, we study nanoindentation and scratching in an Fe (1
0 0) surface. We find an indentation hardness of 20 GPa in good agreement with experiment …

The mechanical responses of single crystalline Body-Centered Cubic (BCC) metals, such as
molybdenum (Mo), outperform other metals at high temperatures, so much so that they are …

Using molecular dynamics simulation we study scratching of Fe crystals by a hard repulsive
tip. Three surface orientations–(1 0 0),(1 1 0), and (1 1 1)–are studied with two scratch …

The study of dislocation nucleation in close-packed metals by nanoindentation has recently
attracted much interest. Here, we address the peculiarities of the incipient plasticity in body …

Using molecular dynamics simulation, we study the nanoindentation of three hcp metals:
Mg, Ti, and Zr. Both the basal and two prismatic surface planes are considered. We focus on …

Atomistic simulations of (001),(110), and (111) nanoindentation are performed to investigate
anisotropic effects in elastic and incipient plastic behavior under nanoindentation. We …

The nanoindentation hardnesses and stacking fault energies (SFE) for pure and alloyed Au
are determined from classical molecular dynamics simulations. Rather than a traditional …

Using molecular-dynamics simulation, we study the scratching of Ti and Mg crystals by a
hard tip. Both the basal and a prismatic surface orientations are considered. We focus on the …

Using molecular dynamics simulation we study the influence of grain boundaries on the
indentation and scratching of Fe crystals by a hard repulsive tip. By comparing the results for …
