These stresses do not exceed the known fatigue strength
of stainless steel (~300 MPa).
As revealed in Figure 15, the rotor speed w, gas temperature T, and fatigue strength
coefficient [[sigma]'.sub.f] are the leading factors on the fatigue life of turbine blisk as the effect probabilities are 32%, 25%, and 21%, respectively.
As previously mentioned, fatigue strength
of every welded detail depends on imperfections inside the weld and local stress concentrations due to the effect of detail geometry or the notch effect inside weld.
improvement by ultrasonic impact treatment of highly stressed spokes of cast aluminum wheels.
Furthermore, the fatigue strengths
for alternating and pulsating loading in and transverse to the fiber orientation and for shear loading were implemented.
Data for prime glass fiber reinforced nylon 6 (PAGF) from a previous study  are presented as a reference to demonstrate the effect of recycling on tensile and fatigue strength
of the nylon compounds.
To assess the effect of grouped arrangement with reduced stud spacing, the previous experimental results on fatigue strength
of shear connection were utilized (Lee et al.
This proportion reduces the alloy's density, and also increases such mechanical properties as strength, stiffness, toughness, and fatigue strength
by more than 30 percent.
The effect of preloading and its sign on the fatigue strength
and fatigue life is evaluated.
