Green strain definition

A representation of deformation tensors in curvilinear coordinates is useful for many problems in continuum mechanics such as nonlinear shell theories and large plastic deformations. Let denote the function by which a position vector in space is constructed from coordinates . The coordinates are said to be "convected" if they correspond to a one-to-one mapping to and from Lagrangian particles in a continuum body. If the coordinate grid is "painted" on the body in its initial configur… WebBritannica Dictionary definition of STRAIN. 1. [+ object] : to injure (a body part or muscle) by too much tension, use, or effort. I strained my back trying to lift the couch. Too much computer work strains the eyes. He strained a muscle in his leg. — compare sprain. 2. : to try very hard to do or get something.
