STRESS-STRAIN FIELD NEAR THE NOTCH TIP OF A RUBBER SHEET

Analized in this paper is the elastostatic field near a notch tip in a rubber-like thin sheet.The asymptotic equations for the notch tip field are derived based on the constitutive relation given by Ref.1.Near field solutions are obtained in regions that decreases and increases in size as the notch tip is approached.Their singular character depends on the constitutive parameters as well as the angle of notch that is evaluated numerically.
