Abstract : Failures of plastics, particularly molded parts, frequently initiate at discontinuities in the structure, such as holes and notches. To alleviate this problem, the engineer frequently designs the part with large radii, or uses a highly ductile material. Little attempt has been made to determine how plastics behave under conditions of concentrated stress. This paper discusses an experimental technique and results obtained on several polymers.
