In fluid mechanics, simple shear is a special case of deformation where only one component of velocity vectors has a non-zero value:
And the gradient of velocity is constant and perpendicular to the velocity itself:
,
where is the shear rate and:
The deformation gradient tensor for this deformation has only one non-zero term:
Simple shear with the rate is the combination of pure shear strain with the rate of and rotation with the rate of :
Important examples of simple shear include laminar flow through long channels of constant cross-section (Poiseuille flow), and elastomeric bearing pads in base isolation systems to allow critical buildings to survive earthquakes undamaged.

Famous quotes containing the word simple:
“It is a curious emotion, this certain homesickness I have in mind. With Americans, it is a national trait, as native to us as the rollercoaster or the jukebox. It is no simple longing for the home town or country of our birth. The emotion is Janus-faced: we are torn between a nostalgia for the familiar and an urge for the foreign and strange. As often as not, we are homesick most for the places we have never known.”
—Carson McCullers (19171967)
