Static force analysis only works when the materials being modeled are well known. Titanium dioxide concrete is a novel material—and, from the article’s text and subsequent research—appears to have a narrow effective range before integrity issues appear.
- antod 8y agoStatic force analysis is independent of the materials (well except for the weight of those materials). It is working out what the loads will be on each member. Designing how those members resist/react to those loads is dependent on the material though.
- WalterBright 8y agoKnowing the strength of materials is pretty darn basic.
- my_username_is_ 8y agoI would disagree. System failure modes can be quite complex. Yes you may have a good approximation of a material's Ultimate Tensile Strength through lab testing (although it isn't a single number and can be affected by a lot of variables, so it's usually designated as a range). But if your material yielded in a way that didn't account for, it could affect the loading on a different member, and trigger an issue with an entirely different part. Real world systems are more complex than your freshman year Statics assignments
- WalterBright 8y agoActually, I worked for Boeing on gearbox design. So I am fairly aware of strength of materials and did a lot of such computations. If you're unsure of the strength, you use the minimum guaranteed value. You don't use materials for critical pieces for which you don't have any data. That would be incredible incompetence. Again, what I am talking about is using statics to determine the minimum loadings to check against the computer models, which should predict higher values or they are wrong. This is not difficult.
