shear stress

Also shear·ing stress

[sheer stres]

noun

Physics.

1. the external force acting on an object or surface parallel to the slope or plane in which it lies; the stress tending to produce shear.

shear stress

noun

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

shear stress

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

First recorded in 1870–75

Example Sentences

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.

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."
