FEA when applied to solid mechanics / structural engineering result in the solution to the equation $$ F = K\cdot x $$ $F$ being the forces, $K$ the stiffness of the system and $x$ represents the resulting displacement.
Now if I were to analyse a live experiment where, lets say, I am applying a point load to a beam, gradually increasing in magnitude. As the load increases the deflection in the beam increases.
Using some sensors and data-acquisition system, if I were to read this load, into a FE program, then I would have, in the equation above, a scenario of load which updates, every few seconds, and this should result in new solution to the FE equation. Also, the actual displacement values can be read using a displacement sensor and fed to the FE program for validation / model updation.
This creates kind of a loop, and completes the definition of real-time FE solver.
Would such a system have any practical use?
