    AnnotationA straightforward application of the new triple decomposition of the local relative motion near a point to 2D velocity fields is presented. Unlike the Cauchy-Stokes double decomposition of motion into a pure straining motion and a rigid-body rotation the triple decomposition of motion aims, moreover, at the extraction of an effective pure shearing motion. It results in a more detailed flow description as the third term is responsible for a specific portion of vorticity labelled "shear vorticity" and for a specific portion of strain rate labelled "shear strain rate"
