Theory of Stress Concentration for Shear-Strained Prismatical Bodies With Arbitrary Nonlinear Stress-Strain Law

Journal of Applied Mechanics, Transactions ASME, 1961
Knowledge of stress concentration is very important for engineers in many practical cases. But the stress-concentration factors for Hooke’s law often cannot be used because most technical materials have stress-strain laws deviating from Hooke’s law.

Breakdown of the Schmid Law in BCC Molybdenum Related to the Effect of Shear Stress Perpendicular to the Slip Direction

open access: yesMaterials Science Forum, 2005
The breakdown of the Schmid law in bcc metals has been known for a long time. The asymmetry of shearing in the slip direction 〈111〉 in the positive and negative sense, respectively, commonly identified with the twinning-antitwinning asymmetry, is undoubtedly one of the reasons.

Scaling Laws for Wall Shear Stress Through Stenoses Under Steady and Pulsatile Flow Conditions

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2001
Most patients with atherosclerosis exhibit isolated stenoses of one or more epicardial coronary arteries. The wall shear stresses produced in high-grade stenosis are important in the understanding of atheromatous plaque rupture and thrombosis. This study is designed to establish a method which can be used to scale the different wall shear stresses ...

On the theory of stress concentration for shear‐strained prismatical bodies with a non‐linear stress‐strain law

Mathematika, 1975
The system of equations governing the stress in a shear-strained prismatical body are examined and it is shown that, provided the stress-strain law adopts certain multi-parameter forms, the system may be reduced to the Cauchy-Riemann equations. Integration of the system is then immediate and the analysis of the stress concentration round certain ...

The influence of magnetic field on wall shear stress in power law fluid flow of blood

AIP Conference Proceedings, 2021
The profile of wall shear stress in non-Newtonian fluid which power law fluid through a cosine shape stenosis is analysed in this study. This study also reveals the effect of magnetic field as an external force on wall shear stress. Wall shear stress is an important flow characteristic in order to determine the behavior of blood.

DISSOCIATED DISLOCATIONS AND THE SCHMID LAW OF RESOLVED SHEAR STRESS IN b.c.c. METALS

Canadian Journal of Physics, 1967
The dissociation of screw dislocations on [Formula: see text] planes in a b.c.c. metal can lead to unequal shear stresses for glide in opposite directions, while dissociation on [Formula: see text] planes cannot. Glide will occur in the former configuration only if the radius of the core of a partial dislocation exceeds [Formula: see text] of the ...
