Nonlinear structural design using multiscale topology optimization
… by combining topology optimization, computational homogenization and parallel programming into a multilevel design framework. The design problem is posed as a multilevel topology optimization problem: a macroscopic problem that optimizes the constituent volume fraction field and the …

Mechanics of Three-Dimensional Micro-Architected Interpenetrating Phase Composites
… structure surrounded by a matrix. Using computational homogenization, we first predict how resultant coupled stress states in the composite change with the material properties of each individual phase and contextualize the results within traditional stiffness scaling laws. We then …

MACHINE LEARNING FOR CONSTITUTIVE MODELLING
… scale of multi-scale analysis to reduce the computational cost. These surrogate models provide the constitutive law of the micro scale simulations after a training process, called off-line learning. For history dependent materials, the recurrent neural network (RNN) is adopted for the …
