Have you heard of the famous Tacoma Narrows Bridge accident in 1940? The failure was primarily due to aeroelastic flutter, a phenomenon where wind-induced oscillations become self-amplifying. The bridge began to sway and twist in response to the wind, which caused resonance at its natural frequency. This led to increasingly violent oscillations, ultimately causing the bridge to break apart and collapse. If Ansys Mechanical had been used during the creation of the bridge, they could have utlized Fluid-Structure Interaction (FSI) in Mechanical to simulate and analyze the complex interactions between fluid flows and structural components. FSI in bridge design and engineering can predict how wind forces interact with the bridge structure, helping engineers to design shapes and structures that minimize adverse effects like oscillations and vibrations. #structuralengineering #innovation #ANSYS #Mechanicalengineering

Now all you need is a time machine to go back 100yrs and advise them before construction!
This incident highlights the critical importance of conducting thorough design reviews by an independent third-party, especially for significant engineering projects. This kind of avaliation allows us to provide an essential review and validation of complex engineering designs, ensuring safety and reliability.

One of the first catastrophic failure where question marks regarding fatigue and fracture subject began
O mesmo efeito pode acontecer em instalações foto-voltaicas, se não forem observados as devidas variáveis de projeto.
How could have Ansys Mechanical been for the bridge design when Ansys did not exist back then in 1940s 😁 Anyway just joking, a nice demonstration and explanation.
Was it flutter? Resonance? Or limit cycle oscillations resulting from some non-linear fluid structural interaction
