Experimental investigations of large strain deformation processes such as cutting and
sliding have primarily involved analysis of process-level variables such as deformation …

Using in situ high-speed imaging, we unveil details of a highly unsteady plastic flow mode in
the cutting of annealed and highly strain-hardening metals. This mesoscopic flow mode …

Sinuous flow is a recently discovered mode of unsteady plastic flow in the cutting of metal
involving large plastic strains, extensive material folding, and consequences ranging from …

The cutting of metals has long been described as occurring by laminar plastic flow. Here we
show that for metals with large strain-hardening capacity, laminar flow mode is unstable and …

Large strain plastic flow in cutting of metals is studied at multiple length scales using high-
speed imaging and marker techniques, complemented by particle image velocimetry and …

Annealed metals are surprisingly difficult to cut, involving high forces and an unusually thick
“chip.” This anomaly has long been explained, based on ex situ observations, using a model …

We examine large-strain deformation and unsteady flow modes in cutting using high-speed
imaging. For metals which exhibit large workability and strain hardening, the commonly …

We demonstrate a unique mechanochemical effect–change in surface plastic flow by action
of chemical media such as inks and glues–in large-strain deformation of metals. Unlike other …

Tantalum has long drawn the ire of machinist, being particularly difficult to cut. Often referred
to as being 'gummy,'cutting of tantalum is characterized by very thick chips, large cutting …

Surface folding in large-strain deformation of metal polycrystals, mediated by unsteady
sinuous plastic flow, was recently uncovered by direct observations. Here, we examine …
