Researchers have developed a hyperreduction technique to accelerate the process of discovering neural materials using finite element model updating. This method combines intrusive model order reduction with proper orthogonal decomposition and energy-conserving sampling to significantly reduce computational costs during training. The constitutive law is defined by a polyconvex neural network, ensuring stability regardless of trained weights. This approach has demonstrated substantial time savings, reducing training from hours to minutes without sacrificing accuracy, making the discovery of neural materials from structural data more feasible.
