Abstract : The stress distribution of the double-torsion fracture mechanics specimen geometry is presented using a photoelastic frozen stress technique. Isochromatic fringes of a plastic double-torsion specimen under load were photographed and analyzed in the top, middle and bottom planes parallel to the top surface. Principal stress directions for these planes are also given. The relative magnitudes of the principal stresses perpendicular to the crack plane at the crack tip, crack origin and a point midway between the origin and crack tip are shown. (Author)
