Abstract
The stress and strain behavior at notch tips is analyzed with the view of using local values for fatigue calculations. A perfectly plastic, closed form solution is used as a starting point and basis of comparison for the finite element analysis. Maximum stress and strain values for 7075-T6 aluminum were obtained via finite elements and reflection photoelasticity in the plastic zone, and residual stress and strain values after unloading were obtained as well. A uniaxial model was used successfully to predict most of the behavior observed. (Author)
