An izod specimen for the simulation of conditions of plastics use

Abstract

AbstractThe stress concentration and effective flexure stiffness of an ASTM V‐notch Izod specimen is excessive for most cases of plastics use. A more typical stiffness is that of a thin plate in two dimensional bending. Such can be approached with a larger radius and deeper V‐notch. Instead of a V‐notch, however, a double edge notch with the same radius and thickness at the root is recommended. The special advantage of the double edge notch is that the notch at the back edge reduces the energy loss due to the clamp.
