Sentence examples for mean stress value from inspiring English sources

This paper presents a stress based approach to take into account the influence of the mean stress value on fatigue strength of constructional materials.

The paper contains a mathematical model of the material's behaviour under cyclic loading taking into account the dynamics of the fatigue process, including the number of cycles to failure, induced by the mean stress value.

Cycle-dependent relaxation may alter mean stress values and thus affect fatigue crack initiation life.

The present computations are then used to capture the evolution of surface and sub-surface fields for different levels of partial slip, interfacial friction and externally imposed mean stress values.

Several experimental results related to the high-cycle fatigue strength for smooth metallic specimens, subjected to in-phase or out-of-phase biaxial loading with different mean stress values and various ratios of the stress amplitudes, are analysed by employing the C S criterion, its simplified version, and other criteria available in the literature.

Thus, our interpretations are based on proportional rather than absolute differences in mean stress values and distributions.

The computed mean stress and strain values of the stabilized cycle being far from the initial ones, they could be used to get the safety margins of standard design related to fatigue, as well as to get accurate loading conditions needed for the use of more advanced fatigue analysis and criteria.

Normal functional segments at 4 months after MI that remained stable had a significantly higher mean MPR and mean stress perfusion PET value than deteriorated segments (p < 0.001).

Furthermore, dysfunctional segments that improved had a significantly higher mean stress perfusion PET value than dysfunctional segments that remained dysfunctional (p < 0.001).

These values are smaller than those using mean stress as an addition criterion, in which the values are 0.674 and 0.308, respectively.

This allowed values of nominal maximum stress, Smax, and mean stress, Sm, to exceed Su in most tests.
