Nonlinear fluid behavior: from shear thinning to shear thickening

Physica A: Statistical Mechanics and its Applications, 1994
Abstract A phenomenological model is introduced which describes both shear thinning and shear thickening behavior. Consequences of this model are presented for plane Couette (simple shear) flow. The non-Newtonian viscosity and normal pressure differences are discussed for a stationary situation.

Critical behavior of entropic shear rigidity

Physical Review E, 2006
We report on extensive molecular dynamics (MD) simulations of a model for gels in both two and three dimensions. The model consists of randomly cross-linked monomers with a concentration p of cross-links above the percolation concentration so that the system is in the amorphous solid phase. As the concentration of cross-links approaches the percolation

Postbuckling Behavior of Composite Shear Webs

AIAA Journal, 1980
In this paper the postbuckling behavior of multibay composite shear webs is explored. Several test specimens are designed through the use of advanced state of the art design methods taking into account material anisotropy. The panels are subjected to static as well as fatigue loading in a series of well instrumented and carefully conducted tests to ...

Shear Behavior of Woven Fabrics

Textile Research Journal, 1989
In an experimental study on the shear behavior of both gray and finished wool and wool blend woven fabrics, we have investigated the effects of finishing and wetting and changes in four shear parameters—initial shear modulus Go, frictional shear stress σ o, shear rigidity G, and residual shear strain tan θ o.

Shear behavior of geocell-geofoam composite

Geotextiles and Geomembranes, 2021
Abstract In design, internal stability of EPS lightweight fills are provided either by applying load distributing mechanisms (thick pavements or concrete slabs) or using more strong lightweight material through denser EPS geofoam blocks. However, unit weight of the EPS geofoam is a limited parameter. As an attempt to improve the mechanical properties

Dynamic behavior of lung parenchyma in shear

Journal of Applied Physiology, 1996
Dynamic shear properties of excised rabbit lungs were studied by measuring creep deformation after application of a step indentation force to the pleural surfaces by a rigid cylindrical punch. The punch diameter was 9.5 mm, and punch forces were 2,4, and 6 g.

Shear Behavior of Strengthened Beams

2018
Strengthening the reinforced concrete elements using polymer fibers continues to interest many researchers. In this context, an experimental study has been completed to evaluate the reinforcement on shear behavior of beams. Different fiber band positions were applied to beams in nodal zones. The four-point bending tests have been performed. The results

Shear behavior of shear stud groups in precast concrete decks

Engineering Structures, 2019
Abstract In order to study the shear behavior of a group of shear studs placed on a composite beam, a total of 16 pushout tests were conducted, including 4 specimens with cast-in-place (CIP) concrete decks and 12 specimens with precast concrete (PC) decks.

Shearing behavior of curved interfaces

2010
Pipe-jacking and microtunneling technologies are being more widely used over the past decade and there is significant interest to predict the jacking forces and jacking distances achievable in order to achieve more efficient design and construction. This study focuses on the evaluation of the frictional characteristics and factors affecting the shear ...

Singular Behavior of Shear Flow Far from Equilibrium

Physical Review Letters, 1993
A rare exact solution to the nonlinear Boltzmann equation describing rheological phenomena far from equilibrium is reconsidered. We show the existence of a critical shear rate beyond which the solution fails to exist. The implication of this exact result is a singular transition from simple uniform shear flow to a more complex state, perhaps involving ...
