1. 1. Estimation of fatigue life by using a cyclic plasticity model and multiaxial notch correction

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Nils Johansson; [2019]
   Keywords : Multiaxial load; fatigue; notch; elastic-plastic; stress-strain; non-proportional load; incremental Neuber; damage parameter;

   Abstract : Mechanical components often possess notches. These notches give rise to stress concentrations, which in turn increases the likelihood that the material will undergo yielding. The finite element method (FEM) can be used to calculate transient stress and strain to be used in fatigue analyses. READ MORE

3. 2. Continuous Time Fatigue Modelling for Non-proportional Loading

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Sajjan Gundmi Satish; [2019]
   Keywords : Multiaxial Fatigue Loading; Fatigue Analysis; Continuous Time fatigue model; Endurance Surface; Rainflow Counting; Cyclic loading; Cycle Counting; Damage Evolution; High-cycle fatigue; Non-proportional loading;

   Abstract : Fatigue analysis is a critical stage in the design of any structural component. Typically fatigue is analysed during post-processing, but as the size of the analysed component increases, the amount of data stored for the analysis increases simultaneously. READ MORE
