heal.abstract	The elastic stress and strain distribution along the flanks of an internal oblique crack in an elastic plate submitted to simple tension at infinity was studied. The shape of the deformed Griffith crack was previously studied, based on the exact solution of an infinite cracked plate under conditions of plane stress[1]. It was shown, that, besides the angular displacement of the crack axis and the deformation of the crack to an elliptic shape of variable maximum curvature, there is also a lip-slipping phenomenon, where the crack boundaries rotate in a round-about motion. Since this motion is not uniform along the flanks of the crack, the study of the strain-variation along the elliptic boundaries of the deformed crack governs the mode of lip slip and defines the zones of the flanks presenting maximum values of straining. An extensive study of the components of strains along the flanks of the deformed crack was based on defining the tangential to the flanks strain components along the elliptic shape of the crack, whereas for the normal component of strain, on its definition along the effective crack axis. Interesting results were derived from this study giving an insight to the reduction of the curvature of the crack as the loading is increased. © 1988.	en
