This project was a collaboration with a Fortune 100 Heavy Equipment OEM's advanced computer aided engineering team to accelerate the rate of FEA result prediction for design work. The end goal was to have an emulator capable of predicting the stress at a number of critical nodes in the FEA with respect to the modulus of elasticity (E) and ultimate tensile strength (UTS) of the material.
The small number of FEA simulations available for training combined with the complexity of the response made accurately emulating individual nodal responses impossible. The limited availability of simulations also made direct analytics like sensitivity analysis and Uncertainty propagation difficult.
Using mixed input techniques to allow information to be shared across the FEA nodes in order to build a highly accurate emulator. This emulator was accurate enough to run the desired analysis and identify new behaviors, like the bimodal peak below, in the system response.
