The criterion is applied to the simple idea proposed by the authors in a previous note that Gaßner curves can be interpreted as shifted Wöhler curves. The mean stress correction used has been proposed by Smith, Watson and Topper and, more in general, by Walker. By applying the correction, a new expression for the shift factor G is obtained and, through the application of the theory of the critical distances in its point variant, surprisingly G is demonstrated to be valid for both smooth and notched geometries since it does not seem to depend on the geometry, but only on the fatigue exponent and the loading history. Finally, a comparison with the SAE Keyhole test program data is added to substantiate the findings.</p>

https://imechanica.org/node/21991
<div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p>Hi </p>
<p>I have few questions:</p>
<p>1- why most the experimental fatigue studies on metal or metal-composites in the literature were adopted a frequency less than 35Hz (the majority of these test have conducted using 20Hz).</p>
<p>I ran into some articles mentioned that the frequency (0-100Hz) has a marginal effect on the fatigue life of metal. is that the only answer</p>
<p> </p>
<p>2- Is the fatigue loading's frequency has the effect on the adhesive strength in the adhesively bonded metal components, debonding failure, maybe by generating or rising the adhesive temperature in somehow?</p>
<p> </p>
<p>3- apart from the frequency, what is the loading ratio (max.stress/min.stress) that most applicable to structures in service? again in many researchers use the 0.1 ratio</p>
<p> </p>
<p>Thanks</p>
<p> </p>

</p>
<p>
In the field of numerical analysis, the International CAE Conference is the most important event in Italy and one of the leading conferences in Europe. It features two congress days and some Users' Meetings of the main technologies developed by the most important worldwide CAE players, such as ANSYS, Flowmaster, MAGMA, Forge, modeFRONTIER and many others.
</p>
<p>
The International CAE Conference will present the state-of-the-art of CAE in diverse industries. Significant user testimonials will prove how such technologies help increase the product efficiency and ROI. This annual appointment is a major, and efficient platform for designers, analysts, IT managers, engineers, professors, researchers, associations and students involved or interested in virtual simulation tools.
</p>
<p>
An accompanying exhibition will run parallel to the Conference Program. The exhibition traditionally offers a networking platform, where CAE technology solution providers offer their knowledge, advice and expertise to the participants. A special section of the exhibition area will be dedicated to members of associations and scientific bodies, the technical press as well as to hardware vendors who provide the necessary know-how to implement machines and components in order to perform today’s more and more complex analyses.
