Several subroutines have been created and tested in order to improve the applicability. Deformation of the fastener and angle of turn are geometrically related by the following. 4) If the simulation code allows for the input of stress versus total strain, the first point input should correspond to the True Stress at Yield and True Total Strain at Yield. the strain levels are relatively small (less than 5‐10 % true strain). If the amplitude of the total strain is such that we have significant plasticity, the lifetime is likely to be short (Low Cycle Fatigue or LCF; strain life approach). For thermal analysis, the temperature distribution depends upon the heat flux entering the disc through both sides of the disc and wall heat transfer coefficient. For a more details on the analysis of strain gauge techniques see ANSYS Strain Gauge Techniques Report. One is the theoretical analysis and the other is the F inite- E lement M ethod (FEM).
