 Shear stresses will result elongated dimples, which are parabolic depressions that coalesce in planes of maximum shear stress.The depressions point back to the crack origin, and shear influenced failure will produce depressions that point in opposite directions on opposing fracture surfaces.Combined tension and bending will also produce the elongated dimple morphology, but the directions of the depressions will be in the same direction on both fracture surfaces.
