On the correlation between the C and m in the paris equation for fatigue crack propagation

Ermüdungsfestigkeit

“…K c unberücksichtigt bleiben (nach Paris et al [1137][1138][1139] und C 1Y37 Â 10 À14 bzw. Die von verschiedenen Autoren festgestellte Korrelation zwischen diesen Größen ist physikalisch bedeutungslos (Cortie u. Garett [1109]). Hinsichtlich der Werte von C und m bei Schweißverbindungen aus Stahl und Aluminiumlegierung wird auf Radaj et al [70] verwiesen.…”

Reliability Analysis in Fracture Mechanics According to Combined Failure Criteria

“…A common way to integrate these uncertainties is to consider parameters of crack propagation law C and m as random variables. There is a strong correlation ratio between these parameters [11], which can not be independently sampled. Then, it is possible to consider m as random variable and propagate the uncertainty to C according to a linear relationship:…”

Probabilistic prognosis of fatigue crack growth for asphalt concretes

“…34 Since the choice of prior distribution significantly influences the posterior prediction, the ini- 35 tial distribution should be constructed using prior (qualitative) information. However, in many 36 Bayesian applications, the Gaussian distribution is often assumed as the prior distribution, which 37 simplifies the calculation of the posterior distribution. 38 If the random responses of a structural system are monitored and available, the distribution 39 of the system response can be predicted by state estimation techniques.…”
