Lecture 6 - Statics Strength and Stress Concentration Factors
A theoretical, or geometric, stress concentration factor is used to relate the actual maximum stress at the discontinuity to the nominal stress. Normal SCF Shear SCF -S-mak is the maximum stress that develops at the notch. S--O is the nominal …

Fatigue Analysis - UTEP
me.utep.eduStress-Life Approach: (S-N) •The Stress-Life, S-N, method was the first approach used to understand and quantify metal fatigue. •It was the standard fatigue design method for almost 100 years. •The S-N approach is still widely used in design applications where the applied stress is primarily within the elastic range of the material and
Lecture 2 - Shear and Bending Moment and Review of Stress
me.utep.eduTorque, 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.
Lecture Slides - UTEP
me.utep.eduFatigue 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.
