Simple Shear in Solid Mechanics
In solid mechanics, a simple shear deformation is defined as an isochoric plane deformation in which there are a set of line elements with a given reference orientation that do not change length and orientation during the deformation. This deformation is differentiated from a pure shear by virtue of the presence of a rigid rotation of the material.
If is the fixed reference orientation in which line elements do not deform during the deformation and is the plane of deformation, then the deformation gradient in simple shear can be expressed as
We can also write the deformation gradient as

“How many desolate creatures on the earth
Have learnt the simple dues of fellowship
And social comfort, in a hospital.”
—Elizabeth Barrett Browning (18061861)
“In our world of big names, curiously, our true heroes tend to be anonymous. In this life of illusion and quasi-illusion, the person of solid virtues who can be admired for something more substantial than his well-knownness often proves to be the unsung hero: the teacher, the nurse, the mother, the honest cop, the hard worker at lonely, underpaid, unglamorous, unpublicized jobs.”
—Daniel J. Boorstin (b. 1914)
“the moderate Aristotelian city
Of darning and the Eight-Fifteen, where Euclids geometry
And Newtons mechanics would account for our experience,
And the kitchen table exists because I scrub it.”
—W.H. (Wystan Hugh)
