MTS model based force prediction for machining of Ti-6Al-4V
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 The high temperature and severe plastic deformation could promote workpiece material microstructure evolution in the machining process. The material mechanical properties are functions of the material microstructure attributes.

Coronary flow reserve during dobutamine stress in Takotsubo stress cardiomyopathy [PDF]
BMJ Open, 2015 ObjectivesTakotsubo stress cardiomyopathy (TSC) is an increasingly recognised and diagnosed disease, although the underlying pathophysiology is still unknown. Our aim was to investigate the effect of the catecholamine dobutamine on coronary flow reserve (CFR) measured non-invasively in patients with TSC and controls.

Polymer stress tensor in turbulent shear flows [PDF]
Physical Review E, 2005 The interaction of polymers with turbulent shear flows is examined. We focus on the structure of the elastic stress tensor, which is proportional to the polymer conformation tensor. We examine this object in turbulent flows of increasing complexity.

Monolayer oxide enhanced flow stress in nanoporous gold: the size dependence
Materials Research Letters, 2018 Compression of nanoporous gold in situ under electrochemical control reveals that its flow stress can be enhanced by surface coverage of monolayer oxide. Here we present a study on the monolayer oxide induced changes in flow stress of an nanoporous gold,

Squeeze Flow of Stress Power Law Fluids [PDF]
Fluids, 2021 In this paper, we studied the squeeze flow between circular disks of a new class of fluids defined by an implicit relation referred to as stress power law fluids. The constitutive response of these fluids was written expressing the symmetric part of the velocity gradient as a tensorial function of the Cauchy stress.
