Dear All,(adsbygoogle = window.adsbygoogle || []).push({});

I would like to calculate fatigue life for the following:

A SS430F metal component is repeatedly hitting at 0.10mm SS304 sheet with 1 Kg load from 0.20 mm distance.

Assume,

Area of hitting: 5.5mm X 16mm = 88 Sq.mm.

Hitting load = 1 Kg

Tensile strength of 0.10mm SS304 sheet is 515 MPa.

Yield strength of 0.10mm SS304 sheet is 205 MPa.

Hardness of 0.10mm SS304 sheet is 85 HRB.

Expected life of 0.10mm SS304 sheet is 50 crores impact forces.

How to calculate the fatigue life of 0.10mm SS304 sheet.

Kindly help me to solve this problem.

Thanks in advance
