New Test Method for Test Method to Determine Intrinsic Threshold Stress Intensity Range

1. Scope

The test method is used to characterize the conditions of the onset of fatigue crack growth expressed in terms of the intrinsic threshold stress intensity factor range as correlated by the near tip residual stress.

Keywords

Crack Growth Threshold,; Crack Tip Stress

Rationale

The growth of cracks in structural components are typically subject to variable amplitude loads that control the useful life. The application of damage tolerant life methodologies is improved if the threshold for crack growth can be determined to assess the impact of small cycles. The standard will be useful for engineers developing robust structural components.
