A relation of unsolved issues related to crack growth rate curves
No full textThe traditional fatigue approaches, namely, the stress based, strain based and fracture mechanics approaches, being different perspectives from the same fatigue problem have more links in common as usually supposed.
In fact, only four parameters can be considered as being significant in the analysis of any fatigue phenomenon, namely, crack size, driving force (stress range, strain range, J-integral range, SWT parameter, etc.), fatigue lifetime (number of cycles to failure) and probability of failure.
The probability of failure encompasses its twofold interpretation: the scatter of the lifetime given the driving parameter, and that of the driving parameter given the lifetime.
In the different conventional fatigue approaches (S-N field, -N field, crack growth rate curve and Kitagawa –Takahashi diagram, respectively), some of those determining parameters in fatigue are neglected or not explicitly included.
Thus, though four main parameters are involved in the fatigue problem requiring all the different approaches or models to be compatible with each other, at most three of these parameters are considered at the same time.
Thus, a global probabilistic fatigue approach are intended to tackle different cases of fatigue problems encompassing the stress based, strain based and fracture mechanics approaches in a unified way by elucidating the existing relations among driving force, lifetime, probability of failure and initial crack size of the material.
The relevant variables involved in each fatigue problem are recognized, and the transcendence of considering compatibility conditions in the derivation of the different probabilistic models is exemplified.
In order to achieve progress in this direction, the main lacks in solving the problem must be recognized

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
