Abstract:

It can be challenging to design complex dynamic nonlinear engineering systems excited by natural events like earthquakes and wind-induced waves, and thermo-mechanical loadings caused by the use of computers. Multi-disciplinary theoretical foundation and computational tools are developed to address this knowledge gap to improve the reliability of engineering designs. Instead of using the random vibration or simulation approach, this novel concept suggests an alternative to them. Using the enormous computational power available in the metaverse era, several advanced mathematical concepts are integrated producing compounding beneficial effects in developing the concept. For a wider audience, they will be presented conceptually and pictorially without any mathematics. By conducting multiple deterministic analyses using the computer instead of one, engineering designs can be significantly improved. The proposed concept is expected to change the current engineering design paradigm making designs more damage tolerant under dynamic loadings, the most complicated problems faced by engineers.
