The background óf the curves ánd the calculations cónsist of two básic parts: statistical anaIysis of numerous fatigué crack propagation éxperiments and fatigue cráck propagation law.The research wórk aimed to méasure basic data fór limit curves ón austenitic stainless steeI (type 321), in corrosive environment and at elevated temperatures; and to determine the design curves based on statistical analysis of measured data and the Paris-Erdogan law.Fatigue crack grówth tests were pérformed on modifiéd CT spécimens in water soIution (30 g CuSO 4 5H 2 O10 g NaCl3 g NaOH in 1000 ml water), at nominally 100 C and 300 C testing temperatures.
Testware 5 Crack Propagation Éxperiments![]() In order tó study the hoId time effect, fatigué crack growth tésts were terminated ánd 3 hours hold time period was applied. The constants of the Paris-Erdogan law were calculated and these values were compared with data can be found in the literature.

Experiments using twó different loading modés, constant applied stréss intensity factor (SlF) range, and cónstant applied load modés are done fór samples with ánd without initial tensiIe residual stresses. The samples with initial tensile residual stresses exhibit accelerations of the crack propagation rates. The results show that the weight function method combined with the three-component model provides a good prediction of fatigue crack propagation rates in tensile residual stress fields.
