✦ Synopsis

New solutions for stresses due to a pair of horizontal or vertical forces acting symmetrically on the surface of a strip are obtained and shown to be easier to evaluate than those that are available in the literature. The displacements and strains on the surface due to a normal stress distribution on the faces of a crack in the strip are then obtained by using Castigliano's theorem. It is shown that the displacement at a distance larger than the thickness of the strip from the crack is essentially a rigid body movement. The solutions obtained provide a basis for residual stress measurement from measurement of displacements or strains.
