FEA theory - Do you need it in practical design?

The importance of FEA theory in practical design in my discussion with Marco Nawijn allowed us to dive deep into what you need to be a good designer and what to pay attention to when learning FEA. 0:00:00 - Welcome 0:00:56 - Marco's Experience / Background 0:06:00 - Importance of Laboratory Test Benchmarking 0:09:00 - Practical importance of Mathematics 0:13:18 - Conclusions as a substitute for theory 0:17:05 - You can't learn everything... 0:18:34 - Knowing "superstitions" instead of a complete theory 0:23:10 - 3 approaches to using FEA correctly 0:27:13 - Reading FEA documentation and science articles 0:34:05 - Awesome complexities in shell buckling 0:40:40 - Mesh convergence 0:46:36 - What about Nonlinear FEA theory? 0:50:10 - Importance of practical experience 0:54:40 - The real role of math, and how it is portrayed 1:01:31 - Do we agree in the end?
