In mechanics and geology, pure shear is a three-dimensional homogeneous flattening of a body. [1] It is an example of irrotational strain in which body is elongated in one direction while being shortened perpendicularly. For soft materials, such as rubber, a strain state of pure shear is often used for characterizing hyperelastic ...
