The motion resulting from stresses that cause or tend to cause contiguous parts of a body to slide relatively to each other.

The motion of surfaces sliding past one another.

Deformation of a body by translation of one part of it relative to another.

angular deformation of a plane figure without a change in area; a type of transformation in which parallel lines remain parallel, but distances and angles are not preserved.

The deformation of rocks by lateral movement along innumerable parallel planes, generally resulting from pressure and producing such metamorphic structures as cleavage and schistosity. - A zone in which shearing has occurred on a large scale.

The deformation and dislocation of rocks, primarily by ductile means, in response to applied stresses.

Forces that act in opposite directions, such as the sliding that occurs when a body and its clothing come into contact with the surface of a chair. Shear forces are minimal, which allows the sitter to recline without untucking a blouse or shirt. Shear forces are high in a forward-sloping chair when clothing tends to stay with the seat while the body slides forward.

trauma caused by layers of tissue sliding against each other .

Shearing in continuum mechanics refers to the occurrence of a shear strain, which is a deformation of a material substance in which parallel internal surfaces slide past one another. It is induced by a shear stress in the material. Shear strain is distinguished from volumetric strain, the change in a material's volume in response to stress.
