Damage Analysis
The development of micro-cracks on the wheel and damage
under the stress factors which deform the material has been
found out by FE analysis and shown in Fig. 13. It is noted that
the probability of damage of the wheel is around the flange as
shown by FE analysis. Based on the FE analysis one may
mentioned that the dimensions of the flange section should be
enough to sustain the stress. In order to save guard the failure of
material one should look into the design aspects and also the
strength properties. It is also noted that after a fatigue cycle of
1x1020 the damage is only 0.2%. This analysis indicated that
even after a fatigue cycle of 1020, the damage on the component
is only 0.2%. Fig. 14 shows the FE analysis after life cycle. The
fatigue analysis results obtained is shown in Table 3.
