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

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
