In nuclear applications like fission, spallation and fusion, one of the main concerns is that the
structural materials must be able to withstand harsh irradiation conditions. In particular, in …

The ability to precisely control the surface state of a nanostructure may offer a pathway
towards tuning the mechanical properties of small-scale metallic components. In our …

The plastic deformation of micropillars is known to be affected by whether dislocations can
escape easily from the material volume, and the extent to which the dislocations mutually …

Understanding dislocation nucleation is key to controlling the plasticity of a defect-free
specimen. Here, we perform an atomistic study of the strength of various Face-Centered …

Dislocation Based Crystal Plasticity: Theory and Computation at Micron and Submicron
Scale provides a comprehensive introduction to the continuum and discreteness dislocation …

Through in situ scanning electron microscope microcompression tests, we demonstrated
that the strain-rate sensitivity of body-centered cubic single crystal iron pillars will be …

While metal nanoparticles are widely used, their small size makes them mechanically
unstable. Extensive prior research has demonstrated that nanoparticles with sizes in the …

The effect of the specimen size on the mechanical characteristics of material, a phenomenon
commonly referred to as the “size effect”, becomes increasingly important at micron and sub …

Micro-compression testing of focused ion beam fabricated pillars is a popular technique for
mechanical characterization at small scales. However, there are concerns associated with …

A stochastic and rate-dependent response originating from thermal fluctuations over a highly
nonconvex energy landscape is a prevailing aspect of the mechanical behavior of …
