Multiple static or dynamic load cases that represent a full duty cycle are applied to determine the mean stress, stress range
, and von Mises stress throughout the component.
Fatigue lives against the average accepted nominal stress range
data designed for the treated specimens and unpeened specimens are schemed to get the S-N curves which are appeared in Fig 7.
Hence, if a fatigue safety factor of 10 is used on the experimental data, the range of design life is between 2,000 cycles and 77,000 cycles considering a stress range
of 36% SMYS.
The size of these stress cycles is often described by the total change of stress, called stress range
This may include two stress components, but from the convenience and safety point of view is still in a stress range
, Figure 6 a), b), c) the midpoint line shown in curve is [P.
P] is plastic strain range; and [DELTA][sigma] is the stress range
An effective quantified vibration mitigation device would reduce the daily vibration stress range
and thus would increase the fatigue life of the structure.
To calculate shear strength parameters of rock masses based on this criterion, with the saturated uniaxial compressive strength of the intact rock of samples (oci), the value of (m) for the intact rock (mi) and Geological Strength Index (GSI), Hoek-Brown curves in the existing stress range
have been calculated and drawn.
A controlled stress rheometer with a wide shear stress range
and the ability to quickly drop the applied shear stress to a low level probably would be the best choice.
The tendon load bearing capacity was more vulnerable to a tear in the lower half of the physiological ultimate stress range
The stress range
considered for the specimens is 627 MPa, 1.
The effects of increased stress range
from family conflicts and alcohol misuse to increasing mental health difficulties and even domestic violence.
