Hacker News with Generative AI: Failure Analysis

Failure Theory for Materials Science and Engineering (failurecriteria.com)
Three dimensional failure criteria are given for various materials classes. These include both isotropic and anisotropic material symmetries, and are applicable for macroscopic homogeneity. In the isotropic materials form, the properly calibrated failure criteria can distinguish ductile from brittle failure for specific stress states. Although most of the results are relevant to quasi-static failure, some are for time dependent failure conditions as well as for fatigue conditions.

Failure analysis of the Arecibo 305 meter telescope collapse (nationalacademies.org)
Building and operating cutting-edge, custom-designed research facilities presents unique challenges, where prior designs and experience may not be a reliable guide and unprecedented modes of failure can never be fully anticipated.

Ask HN: What are some good publicly available postmortems to read? (ycombinator.com)
I'm looking to read a few (publicly available) postmortems of incidents and accidents. The domain/organization/... doesn't matter too much so long as they are insightful and there's something to be learned from reading them. Bonus points for including a quick note on why you considered them particularly interesting!
