shear strain
shear strainn. Strain resulting from the application of opposing forces in a direction parallel to a surface or to a planar cross section of a body. Also called shearing strain.shear strain
shear strain[′shir ‚strān] (mechanics) Also known as shear. A deformation of a solid body in which a plane in the body is displaced parallel to itself relative to parallel planes in the body; quantitatively, it is the displacement of any plane relative to a second plane, divided by the perpendicular distance between planes. The force causing such deformation. shear strain, shearing strainA deformation in a structural member (measured in radians) resulting from the application of a force in a plane (or line) of a cross section of the member, perpendicular to the length of the beam. |
