shear stress British  

noun

1. the form of stress in a body, part, etc, that tends to produce cutting rather than stretching or bending

shear stress Scientific  

1. A form of stress that subjects an object to which force is applied to skew, tending to cause shear strain. For example, shear stress on a block of wood would arise by fixing one end and applying force to this other; this would tend to change the block's shape from a rectangle to a parallelogram.

2. See also strain

Etymology

Origin of shear stress

First recorded in 1870–75

Example Sentences

Dr Rochev added: "When we investigated the mechanical distribution in the cell layer, we found that shear stress varies along the different functional zones, suggesting a potential role in regulating cell migration, differentiation, and immune responses. When this protection is compromised, as in UC, it could contribute to inflammation and tissue damage."

From Science Daily

When the research team, led by Dr Yury Rochev, School of Physics, University of Galway, investigated the mechanical distribution in the cell layer, they found that shear stress varies along the various functional zones, suggesting a potential role in regulating cell migration, differentiation, and immune responses.

From Science Daily

This snapshot details the shear stress the force may exert on the quark particles that make up the proton.

From Science Daily

The reversible and irreversible crosslinks within the hydrogel adapt to high shear stress during injection, ensuring excellent mechanical stability.

From Science Daily

If the viscosity of some fluids diminishes in response to shear stress, are there other fluids whose viscosity increases?
