It has been well documented that plastic deformation of crystalline and amorphous
metals/alloys shows a general trend of “smaller is stronger”. The majority of the experimental …

Pre-straining defect-free single crystals will introduce heterogeneous dislocation nucleation
sources that reduce the measured strength from the theoretical value, while pre-straining …

Although diamond is the hardest material, it would still be deformed by indenting. Therefore,
investigating its incipient plasticity during the indenting process should be of great interest …

Although nano polycrystalline diamond (NPD) is found with hardness equal to, or even
higher than that of single crystal diamond, there are still some controversies about its …

Using the molecular dynamics simulation method, nanoindentation simulation was carried
out on a variety of nanotwin Cu-Ag alloys with different gradient distribution structures and …

In this work, unirradiated and irradiated model body centered cubic (BCC) and face centered
cubic (FCC) materials are investigated using advanced electron microscopy techniques to …

A single-crystal plasticity model as well as a gradient crystal plasticity model are used to
describe the creep behavior of directionally solidi? ed NiAl based eutectic alloys. To …

Through using molecular dynamics (MD) simulation, nanoindentation simulations of
nanotwin Cu-Ag alloys with multiple different twin spacings were performed in order to …

We present experimental data and simulations on the effects of in-plane tension on
nanoindentation hardness and pop-in noise. Nanoindentation experiments using a …

For actual structural engineering applications of materials, many kinds of extreme conditions
like high-speed dynamic loading, low temperature, high pressure, other than normal ones …
