  Former structural analyst here. :waves: If you worked on consumer products there (aka cars and their components), do you happen to remember what the design-to fatigue life was? I talked with another analyst several years ago who had worked at Chrysler, and he told me they had used 125,000 miles. (I was in aerospace so not sure how many miles comprised a fatigue cycle, etc.)

    Not exactly what you asked, but: I worked as a structural analyst on passenger train cars (metros, LRVs, etc) for a while, as my first job after grad school actually. Depending on the project (client requirements), we designed for 25-35 year lifetimes, with 12-24h operation typical. That usually amounted to millions of kilometers. We had load cases with varying numbers of cycles. Eg curves with light loading might have been millions of cycles, but max (or even over max) loading might have been 10s or 100s of thousands of cycles. All load cases were determined based on on usage stats from the operator and testing conducted to measure accelerations on the operator's infrastructure.
