An unsupervised machine learning approach to reduce nonlinear FE2 multiscale calculations using macro clustering

S Chaouch, J Yvonnet - Finite Elements in Analysis and Design, 2024 - Elsevier
Solving nonlinear multiscale methods with history-dependent behaviors and fine
macroscopic meshes is a well-known challenge. In this work, an unsupervised machine
learning-based clustering approach is developed to reduce nonlinear Multilevel Finite
Element-FE 2 calculations. In contrast with most available techniques which aim at
developing Reduced Order Models (ROM) or AI-based surrogate models for the microscale
nonlinear problems, the present technique reduces the problem from the macro scale by …
