Fatigue Analysis - UTEP

Stress-Life ApproachFor Extreme EnvironmentsFatigue AnalysisStress-Life ApproachPresented by Calvin M. Stewart, PhDMECH 5390-6390 Spring 2021 Outline Fatigue Loading Stress-Life Approach Unmodified Endurance Limit Endurance Limit Modifiers Mean Stress Solving ProblemsFatigue LoadingFatigue Loading Components, structures, and vehicles are subjected to quite diverse load histories. Some load histories may be simple and repetitive. Others may be completely random. The randomness may contain substantial portions of more deterministic loading. For example, the ground-air-ground cycle of an aircraft has substantial similarity from flight to LoadingGround-Air-Ground cycle of AirCraftRepetitiveRandomnessFatigue LoadingOffshore StructuresAircraftEnvironmental EffectsFatigue LoadingTypical Load Histories From Actual Ground Vehicle ComponentsFatigue LoadingA Typical Load History of Short-Span BridgeFatigue Loading These load histories are typical of those found in real-life engineering situations.

•Low Cycle Fatigue (LCF) - when N f is in the range of 100 to 103. •High Cycle Fatigue (HCF) - when the number of Cycles to failure, N f, is in the range of 103 to 106. •Infinite Life - when N f is equal to or greater than 106.

Lecture Slides - UTEP

Fatigue Loading of Helical Compression Springs It has been found that for polished, notch-free, cylindrical specimens subjected to torsional shear stress, the maximum alternating stress that may be imposed is constant and independent of the mean stress. Many compression springs approach these conditions.

Torque, T is a moment that causes a twisting deformation about an axis. The twisting deformation can be defined using the Angle Of Twist, Theta c- Torsional Shear Stress develops through the cross section. The maximum torsional shear stress is found on the outter surface.
