Using "target values" to work back the final strcuture?
Using "target values" to work back the final strcuture?
(OP)
From recent chat with a fellow engineer, he mentioned that some of the coolest structures (organic shapes) today are designed with the method "target values." In theory, it defines the ultimate stresses and deformation loads, then works back to the final structure. It is different from the conventional practice of using X,Y,Z load combinations and then optimize the structure.
Anyone knows where I can get more info. on this subject? Is this a method you used? May you share?
Thanks!

Model all that up in a competent FEA optimising package, press the go button, wait for the answer to pop out. The quality of the result depends largely on the quality of the analyst.
Used all the time in the automotive industry.

Was this developed in China as a form of reverse engineering?

There's also a theorem that says if you know what your loads are and you know the material properties, and a few other things, then you can work out the minimum volume of structure that is possible. That's all I know about that. It sounds like some sort of virtual work calculation.
