Finite element modeling of fatigue life of steel wire

الملخص EN

In this work, bending fatigue life of steel wire has been studied using finite element modeling by ANSYS program.

To verify the finite element results; a fatigue setup was designed and constructed, and the wire was tested using this setup.

The results showed that the fatigue life of the wire that bent over the smaller bending diameter has the lower fatigue life, while increasing the bending diameter has a great effect on increasing the fatigue life of steel wire.

The finite element results were almost near the experimental results with an accepted percent of deviation.

The other values such as, equivalent (Von-Mises) stress, elastic strain, plastic strain, total strain, and the total deformation were estimated using finite element modeling.

The Von-Mises parameters results showed that the wire bent over the bigger bending diameter has the lower values in which affect its fatigue life in a positive way.
