Fatigue Life of 0.10mm SS304 Sheet | Sathish Rosario

AI Thread Summary
The discussion focuses on calculating the fatigue life of a 0.10mm SS304 sheet impacted by a SS430F component under a 1 Kg load. Key parameters include the tensile strength of 515 MPa, yield strength of 205 MPa, and a target life of 50 crores impact forces. Participants suggest identifying the fatigue limit, correcting factors for conditions, and mean and amplitude stresses to determine safety factors using criteria like Soderberg, Goodman, or Gerber. Practical step-by-step examples are requested to aid in understanding fatigue calculations. The conversation emphasizes the importance of these calculations for assessing material durability under repeated stress.

Dear All,

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

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
