Nice to meet you.
I would like to ask you about the L-shaped flat spring. I’m thinking of making a SUS flat spring with a thickness of 0.1 (or 0.2 to 0.3 mm), but I don’t know how to find the displacement. Since it is stopped at two points as shown in the figure, can the displacement be calculated by using the cantilever’s calculation formulas?
Is it okay if the second moment of area and the section modulus are I = bt ^ 3/12?
In addition, I would like to know the lower and upper-stress coefficient of SUS316, 304, and stainless steel strips and the number of repetition diagram.

Thank you for writing!
I think it is okay to calculate it using the cantilever’s calculation formulas. It is said that mt = 0.1 to 0.3, but depending on the direction in which the load P is applied, b (width) will be 0.1 to 0.3 instead of t. In addition, there is a 10-million-time diagram of the service life of SUS, so we will send it to you.
We are happy to answer any inquiries regarding technology, specifications, materials, etc. Please feel free to ask.
