The tensile strengths of plastics with drilled holes can be analyzed by treating the hole as a nucleus in flaw generation. The analysis is accurate for hole diameters less than the inherent flaw size. Above this value the tensile strengths define a single curve when plotted on a reduced variable scale. Using the analysis in its linear range facilitates evaluation of the Griffith parameters. From such an application it was found that plasticizers markedly reduce the values of the Griffith parameters while affecting tensile strengths only slightly. Temperature has a similar effect.
