A Fourier-related FE2 multiscale model for instability phenomena of long fiber reinforced materials

This work aims to develop a computationally efficient multiscale model to accurately simulate and analyze the instability phenomena of long fiber reinforced composites. The multilevel finite element method (FE2) based on the homogenization theory is adopted to realize the real-time interaction between the microscopic and the macroscopic levels. To increase the computational efficiency in the microscopic level and control the nonlinear...
