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.

Time scales in shear banding of wormlike micelles [PDF]
, 2002 Transient stress and birefringence measurements are performed on wormlike micellar solutions that "shear band", i.e. undergo flow-induced coexistence of states of different viscosities along a constant stress "plateau".

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,

Effect of changing strain rate on flow stress during hot deformation of type 316L stainless steel [PDF]
, 2008 ompression testing has been used with ramped changes in strain rate during deformation, and with changes in strain rate between double deformations to study their effects on flow stress.

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.

Stress-Minimizing Orthogonal Layout of Data Flow Diagrams with Ports [PDF]
, 2014 We present a fundamentally different approach to orthogonal layout of data flow diagrams with ports. This is based on extending constrained stress majorization to cater for ports and flow layout.
