Theoretical analysis shows that the amount of slow growth occuring prior to fracture in a plane stress tension specimen, subjected to a subcritical stress intensity level, is affected by the following parameters: 1. ductility and rheological sensitivity of the material, 2. rate of loading, 3. initial crack size, and 4. geometrical configuration of the test. These parameters enter the governing nonlinear differential equation which describes the quasi-static crack extension in a rate-sensitive Tresca solid. Examples of numerical integration are given and employed to predict the maximum fracture toughness attained in a plane stress tension test.
